firefox crashes after changing gnome theme

[Przemek K.]

Binary package hint: firefox

Firefox freezes when I change the Gnome theme.
I have many tabs opened in Firefox and changing Gnome theme while having Firefox running in the background almost always makes it freeze, and then I have to kill it.
I have Ubuntu 7.04 and Firefox 2.0.0.4

Update: the bug is still present on Firefox 3 in Ubuntu 8.04

Thank you Przemysław Kulczycki 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 tried with a new clean profile - at first nothing happened. I tried again a few times and clean-profile firefox froze, just as before.
Steps to reproduce:
1) Open about 20 tabs in Firefox
2) run gnome-theme-manager
3) Change your Gnome theme to anything else
4) Voila - Firefox will now eat 100% of your CPU and freeze for pretty long time.

It doesn't crash though. It just freezes for so long that I have to kill it.
Here's my gdb output.

[Przemek K. (azrael)]

I've created a new test user and the bug still appears.

Hi rzemysław Kulczycki,

Could you please reproduce the crash and upload the report that probably will be generated during the crash and that should be located at /var/crash/ to https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/124054/+addcomment as the gdb log you uploaded doesn't show useful information.

Thanks in advance.

I've run firefox with strace - the log is attached (though it's huge - 8.7MB after unpacking).
I've opened 20 tabs in my firefox on a clean profile on a new test user, I changed my gnome theme while firefox was running, and then firefox was not responding for about 2 minutes so I killed it.
Maybe this log will tell you something.

[Alexander Sack (asac)]

can you reproduce this issue? Can you add step-by-steps instructions how to do that?

Thanks,

sorry ... but i couldn't reproduce with instructions in https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/124054/comments/2 ... i will retry tomorrow though.

I tried to freeze Firefox with the instructions from the second comment, but nothing. It did took a while to change the theme, but Firefox continued to work normally after that.

Tested in Gran Paradiso alpha 7. I will try to reproduce it in Firefox 2.

It seems to be fixed in intrepid.

Just had Firefox crash on me when changing themes through the "Appearance Preferences" applet. I'm using Intrepid Ibex (8.10).
