nautilus assert failure: *** glibc detected *** nautilus: double free or corruption

I get this message when I try to open Nautilus with root privileges in Karmic:

nelson@nechus:~$ sudo nautilus
** Message: Initializing gksu extension...

So I opened the following thread at ubuntuforums:
http://ubuntuforums.org/showthread.php?p=7863897#post7863897

Eventually, I solved this problem thanks to corncob's suggestion to type "sudo su" to change to the root prompt and then typing "nautilus".

I restarted my system and ran 'gksudo nautilus'. It ran fine once, but after closing it and trying again, I also get a segfault. Backtrace attached
Also, note that the sudo su, nautilus method also produces a craah.

This seems to have something to do with libnautilus-brasero-extension.

Possibly related:

Typing sudo su and then nautilus worked only once. Now I get this output:

Same issue here. The suggested commands are not working.

I am also having the same problem with Karmic, but the workaround mentioned is not working. Here is the output for sudo su then nautilus.
karl@karl-desktop:~$ sudo su

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

@ Chris:

From Bug #420093:

http://launchpadlibrarian.net/30961326/valgrind.log

valgrind log obtained by running:

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log gksu nautilus

Although, it might just be getting info on gksu, not what we really want to look at... Dropping to to root and running just Nautilus doesn't seem to reproduce the crash though...

Andrew - thanks, but that only shows a problem in gksu. It doesn't show any issue in nautilus unfortunately.

Chris, was there something wrong with my backtrace in comment #3?

Yes, it's of a completely separate crash.

Will this backtrace suffice?

What measures you would recommend on debugging "gksudo nautilus" not working?

This certainly does seem to be related to brasero. If I downgrade to the Jaunty versions of both brasero and libbrasero-media0 that seems to solve the "nautilus as root" problem (both from cli and using the gui 'nautilus-gksu').

I must say however that it's not even a decent work-around because you must also downgrade to the Jaunty version of rhythmbox and it crashes on Karmic.

Just a heads up as far as having this assigned to brasero, maybe more specifically libbrasero-media0. I haven't tried to parse the differences between versions 2.27.91-0 and 2.26.0-0 (not sure what I'd be looking for anyway).

It is.. Try look at this bug https://bugs.launchpad.net/ubuntu/+source/brasero/+bug/422041.. It's the bug I reported but I don't know how to do the valgrind thing.. I tried but it doesn't seem to work...

I've got the same problem (I mistakenly reported a duplicate #424714)
I'm guessing it won't shine much light on the situation, but here's what I got:

Chris, is this the type of log you need for the bug? By the way, sudonautilus is simply a script that contains "sudo nautilus". My apologies in advance if this is not what you need, as I don't usually participate past describing bugs I have experienced. :-)

In the meantime I've sent this report at https://bugzilla.gnome.org/show_bug.cgi?id=594914 ; could somebody get a valgrind log and attach it to the report or send it upstream? Thanks in advance.

AFAIK, it affects nautilus, not brasero.

the issue is fixed in 2.28 in karmic

gksudo Nautilus (and for that matter "sudo nautilus") work on my setup.

gksudo nautilus now works for me as well but on exit it still segfaults

#31 (Sebastian): if the latest is 2.28, (and mine's 2.27.91), why aren't I getting it thorough update-manager?

This is fixed with latest nautilus (1:2.28.0-0ubuntu2) and latest brasero (2.28.0-0ubuntu1) in Karmic, so I guess that the status could be set to fix released

My system is daily updated & this warning is still there with nautilus (1:2.28.0-0ubuntu2):
