Bug Description

Binary package hint: flashplugin-nonfree

Upgraded the following packages:
flashplugin-nonfree (9.0.124.0ubuntu2) to 10.0.1.218+10.0.0.525ubuntu1~hardy1
Ubuntu 8.04.1
Kernel 2.6.24-19-generic

Get immediate crash at this address: www.euronews.net Page won't even load. Firefox just goes down.

Had no problems with Flash or Firefox up to this point. The above page is a favorite spot I visited often.

After reading the notes on the update, I decided to file a separate bug report. Perhaps the older plugin should be made available in the repository? Until this problem straightens out?

I can confirm this one, Firefox has just begun to close itself randomly (well, when browsing websites including Flash) after that update.

I am currently running Intrepid (also using Flash v10 beta 2) and I can confirm this behaviour, using Firefox 3. Another site that crashes 100% reproducibly: http://polidics.com/

Tested on two computers, a) Dell Inspiron 510m - Pentium M, Intel 855GM; b) Dell Dimension 1100 - Intel Celeron, NVIDIA 5200 PCI.

Steps to reproduce:
1. Visit http://polidics.com

Results:
1. Firefox immediately crashes with a segmentation fault (no debug messages).

Tested the following scenarios:
1. With compiz & without any compositing managers - no difference
2. With & without libflashsupport (see bug #192888) - no difference
3. With & without pulse_pcm configuration (see bug #198453) - no difference
4. With & without "hardware acceleration" enabled within Flash preferences - no difference

The previous version of Flash v10 (beta 1) worked reliably, without crashes on these sites, under two conditions:
1) when using the pulse_pcm ALSA plugins without libflashsupport
2) without pulse_pcm configuration set or libflashsupport (bypasses PulseAudio and only works when PulseAudio server is suspended)

Conclusion:
a) This bug is a regression that occurred between beta 1 and beta 2 of Flash v10.
b) These crashes are *not* related to PulseAudio, so please do not mark as a duplicate of #192888.

I'm anticipating that 64bit users will not notice crashes on these sites - presumably because of nspluginwrapper. Following from my earlier proposal to use nspluginwrapper on 32bit Ubuntu (to fix PulseAudio & libflashsupport problems, see bug #192888), I have created a thread on the Ubuntu Forums with instructions to test the i386 nspluginwrapper package here: http://ubuntuforums.org/showthread.php?t=856764

My rationale for using nspluginwrapper is simple: if Adobe Flash itself has a bug, we cannot fix the bug directly, as it is a closed source product. If we can mitigate or stop crashes using nspluginwrapper, however, then it should be considered for use on all architectures. From my testing of nspluginwrapper i386 on affected sites, these crashes have completely stopped and Flash content appears to work correctly.

As crashes remain after uninstalling libflashsupport, this is not libflashsupport-related.

with a clean profile. In Hardy and Intrepid i get the site and it
works fine. will attach a screen shot of the Hardy one since Intrepid

I can almost confirm that www.euronews.net doesnt open.
I can open the page but it goes down after it loads. but this can be
caused by an extension. Please list all extensions and wher eyou got

Ok, for my regular profile I only use Adblock Plus. I have done further testing and discovered:

Using a fresh profile in every case:
1. Firefox 3 (Ubuntu version) exhibits this bug
2
. Firefox 3 (upstream version) exhibits this bug
3
. Firefox 2 (Ubuntu version) does *not* exhibit this bug.
4. Firefox 2 (upstream version) does *not* exhibit this bug.

Therefore it seems there is some kind of conflict between Firefox 3 and Flash 10.0.0.525 (and it's not the fault of Ubuntu's patches, as the upstream build is the same).

Some users have reported that htttp://polidics.com site triggers this crash, but others have not. It crashes 100% reproducibly on both my systems (intel and nvidia driver), though sometimes the crash is triggered only when you begin scrolling the page. With nspluginwrapper, the crashes stop completely, and Flash appears to work without issue.

It would help if every user that reports on this bug ensure they let us know their version of Ubuntu (32bit vs 64bit) and in the case of 32bit whether they are using nspluginwrapper or not.

I can confirm also with another site, Jupiter Broadcasting, crashes firefox immediately on opening. Was fine immediately before flash upgrade to flash 10.0.0.525, 4 hours ago. I am running 32 bit hardy with a core2duo, with nvidia new driver, compiz, and a dual monitor setup in case any of that helps triangulate the problem.

Not one of these sites crashed for while using Firefox 3 or Epiphany from hardy-proposed with the flash plugin from hardy-backports. I've also installed nspluginwrapper on at 32 bit installation.

dashua,

Flash 10 has been removed from "hardy-backports" today, that's the reason why you're not seeing any bugs.

Michael Onnen posted this link (in the wrong bug) that's relevant to this bug: http://blogs.adobe.com/penguin.swf/2008/07/addessing_wmode_crashes.html

In summary: it's a bug in Firefox 3, fixed in nightlies since 2008-07-08. I tested the nightly build from that date on a fresh profile, and indeed the crashes have stopped on affected sites - although Flash content flickers very strangely and parts of the video do not update properly.

This bug still needs to be addressed in Intrepid, and it is fixed for Hardy (since the backported package was downgraded to Flash 9).

Conn O Griofa (psyke83) wrote :

I have linked the appropriate upstream bug - it's a problem with Firefox 3's "windowless mode" support. This issue will also affect new releases of swfdec that support windowless mode. I will also nominate Firefox for this task, as it is the source of the problem in this case, not Adobe's Flash.

This isnt high priority but either way Hardy has new update for flash
in repos back to 9 if i read it properly so please use that one. If
you got flash beta from flash this bug shouldnt be here at all.

Never mind i see wher eit says from Hardy. but Scott pushed a new
flash to downgrade as flash+64 bit seem to have most issues due to
libflashsupport. Also most sites may not have support for flash 10 yet.
