MASTER firefox crashed [@nsTextFrame::Paint] [@nsContainerFrame::PaintChild] [@nsContainerFrame::PaintChildren]

A proper reinstall of Gutsy from the Tribe 2 fixed the problem.

I think that this bug can be closed.

Thank you for your report.

we are closing now this report, please, reopen it at any time if you
have more related info.

Thanks for your contribution. Don't hesitate to submit new crashes,

I have also a crash of firefox. It shows the following error:

(gecko:10966): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Arial 12'
Segmentation fault (core dumped)

On which version of Ubuntu are you? And did you install Ubuntu from the CD or from a dist-upgrade?

sorry forgot to add,
I'm using gutsy, installed from tribe 3 cd.

I have installed all the new updates,

and firefox starts up, asks about sessions and even start to load pages and then crashes

using kubuntu

(sorry, should be able to change comments)

It seems to be a font problem. I can't confirm the bug has it now works after install of Ubuntu Gutsy Tribe 2.

It would be great if somebody that use Kubuntu Gutsy Tribe 3 can confirm this.

Thank you Mertiki and thomas coopman for submitting this report.

Could you please try to obtain a backtrace by following the instructions
on [1], or upload the crash report that probably was generated during
the crash and that should be located at /var/crash/ to [2].

Please indicate which extensions/plugins do you have enabled; and if
this crash is reproducible describe the steps that lead to it (it is
very important for us to have a test case for each crash).

This will greatly aid us in tracking down your problem.

Thanks in advance.

I actually can't reproduce the crash so I think that only thomas can.

Here's how to do a backtrace :

Forget my link : https://wiki.ubuntu.com/Backtrace

https://wiki.ubuntu.com/MozillaTeam/Bugs is the good link.

We are going to close this report as seems that it's no more reproducible. Please feel free to reopen when you have more information at hand.

Don't doubt to report any other crashes/issues you might have in the future.

Further information can be found at [1].

Getting the same crash (mostly when scrolling) with a fresh install of Gutsy Tribe 5 Kubuntu. My Gutsy Tribe 5 Ubuntu worked fine, so I think it might be Kubuntu-specific.

Terminal Output before crash:

(firefox-bin:10099): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Serif Oblique 7.5'
Segmentation fault (Core dumped).

There is no crash report in /var/crash/, but I made (and attached) a debugging log as described in https://wiki.ubuntu.com/MozillaTeam/Bugs.

Changing my font from DejaVu Serif to DejaVu Sans fixed the issue for now.

reopened

Thank you Rico Sennrich for your report.

I think we need a test case to reproduce this crash. I've tried it by setting the fonts to DejaVu Serif as suggests Rico and I'm not able to reproduce the crash.

Perhaps this helps reproducing the bug: not every website causes a crash, but this one invariably did when scrolling down:

Also, please note that I didn't have any issues with Ubuntu Gutsy Tribe 5, but only with a fresh install of Kubuntu Gutsy Tribe 5 (haven't tried earlier versions).

Ok, I can reproduce this. I am fully up to date with Gutsy Tribe 5 as of September 5, 10:30 PM, Mountain Standard Time.

I moved my .mozilla folder aside and do the following:

1) Run firefox this way -- I can try another way if a dev prefers it
 /usr/lib/firefox/run-mozilla.sh -g /usr/lib/firefox/firefox-bin -d gdb 2>&1 | tee gdb-firefox-crash.txt

2) Enter the debugging info into gdb as per https://wiki.ubuntu.com/Backtrace

3) I don't import any bookmarks from other browsers. (1st time setup because I moved ~/.mozilla)

4) Paste in URL http://www.et.byu.edu/groups/it466/schedule.htm

5) Double click "Google Concept Mapping" in the first notes cell. Firefox now crashes

6) Enter the rest of the gdb stuff from the wiki

At least tonight I can reproduce this crash every single time. :-)
Since I moved my .mozilla folder, I don't have any Firefox plugins installed. I also removed the flash and java plugins prior to running this test (it crashes exactly the same with them installed or not).

System notes:
P4 3 GHz, 1GB RAM
I think this box started as an Edgy box, but it might have been a Feisty beta.
I had turned the computer only only a few minutes before performing this test.
I do have a handfull of freebie fonts in my home directory, but none of them is DejaVu anything.

Other:
When I just run "firefox" from the command line, I get the following:

me@Elements:/tmp$ firefox

(gecko:9962): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Serif Oblique 11.9990234375'
Segmentation fault (core dumped)
me@Elements:/tmp$

Please let me know what I can do. I don't have a ton of time, but could invest a couple of hours if it would help squash this bug. Konqueror is OK, but I miss Firefox.

Note: Iceape (Mozilla replacement?) has the same behavior.

I don't know if this is a solution to the problem, or if I'm just avoiding the problem.

In following a different issue, I found that my computer has problems with some programs and hyperthreading. If I have hyperthreading enabled in the BIOS, firefox crashes, if I disable it, firefox doesn't crash (on the page listed above).

So, I don't know for sure if it's a problem in how firefox treats hyperthreaded machines, or if it's an actual bug in my BIOS or other hardware. Seeing as this machine is a cheap-o HP from Best Buy, my money is on it being a BIOS/hardware error.

Hello,
look at: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/136775

I have Lenovo 3000 N100 with Intel Celeron (without HT). Firefox crashes as well :-(.

I got this same error every time I attempted to open FF:
---------------
ben@ben-desktop:~$ firefox -safe-mode

(gecko:13540): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Times 12'
Segmentation fault (core dumped)
---------------

Removing the Times Truetype font I had installed fixed the problem, and now Firefox starts, though obviously this is not the ideal solution.

Sorry, forgot - that's on a Tribe 5 install from CD, updated via APT to the latest packages. This error started happening for me after the round of updates a couple of days ago.

from what i can tel lthis should be fixed. the changelog of the potential fix is below. If you still see crashes, please open a new bug and once we verified that its still the same crash we can reopen this bug.
