Description of problem:
When I start firefox for the first time (or sometimes a couple of times) after a reboot it encounters a segmentation fault. The crash can happen as early as before all of the (about) 10 saved tabs (different content from day to day) load and as late as a few minutes into the browsing.

Version-Release number of selected component (if applicable):

How reproducible:
Not always, but often enough to be annoying.

Steps to Reproduce:
1. type 'firefox' in a terminal emulator.
2. start using firefox until it crashes
Actual results:
Firefox crashes with a Segmentation Fault

Expected results:
No crashing/segfaults.

Additional info:
Usually, starting firefox for the second time (after a reboot) does not result in a crash (and I have it on for hours). Sometimes it crashes more than once, but not constantly and probably less than 10 times. Basically it seems that if it has been running for about 20 minutes then it probably won't crash.

As per instructions in bug #491765 I'm attaching the backtrace.
Comment 1 Matěj Cepl 2009-04-26 03:59:16 EDT
Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

First of all, could we get output of the command

	rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*

Please also install firefox-debuginfo (debuginfo-install is from
yum-utils package).

	debuginfo-install firefox

You will have to run firefox with a parameter -g for some time. That will start firefox running inside of gdb debugger. Then use command run and wait until firefox crashes. When it happens, you should go back to the gdb and run

	(gdb) thread apply all backtrace

This produces usually many screens of the text. Copy all of them into a text editor and attach the file to the bug as an uncompressed attachment.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

firefox -g backtrace after segfault
Comment 3 Michael Ploujnikov 2009-04-26 15:53:03 EDT
$ rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*

I've already installed everything with 'debuginfo-install firefox' prior to submitting this bug.

The previous attachment was corrupted due to poor copy-pasting.

another backtrace

This is another (seemingly) different backtrace of firefox crashing at startup on my system.
Comment 6 Matěj Cepl 2009-04-27 12:50:38 EDT
Hmm, cannot reporduce here. Does it happen also when you start firefox in safe-mode? (e.g., run firefox -safe-mode in gnome-terminal)
Comment 7 Michael Ploujnikov 2009-04-27 19:41:12 EDT
I tried two times (two reboots) and I wasn't able to reproduce this by running 'firefox -safe-mode'.

OK, then I have to blame some of your extensions/plugins then.

Closing as NOTABUG (that is, not OUR bug).
