core dump from firefox?
Output of the command
rpm -qa \*xulrunner\* \*firefox\*
Sorry, I tried to be helpful and not ask you to do more work, but I am not able
to dissect your core file, so I have to ask you for your help.
Please install firefox-debuginfo (debuginfo-install is from
Then run firefox with a parameter -g. That will start firefox running inside of
gdb debugger. Then use command run and do whatever you did to make firefox
crash. When it happens, you should go back to the gdb and run

Thanks in advance.
I installed firefox debuginfo and ran firefox with -g as requested.
But I get the following warning... is this expected?
Missing separate debuginfo for /usr/lib/firefox-3.0b5/firefox
Try: yum --enablerepo='*-debuginfo' install
As far as reproducing the problem, I've tried the same steps without
a crash. Why can't gdb be run on the original core file now that
debuginfo is available?

a) It is horribly complicated -- I have discussed it with gdb maintainer here,
and it is something which is very complicated and not scriptable.
b) There are still some debuginfos missing. Please, follow the advice in the top
of the backtrace and run (as root):
debuginfo-install acl.i386 alsa-lib.i386 attr.i386 audiofile.i386 avahi.i386
bug-buddy.i386 bzip2.i386 dbus-glib.i386 elfutils.i386 esound.i386 expat.i386

libselinux.i386 libxcb.i386 nspr.i386 nss.i386 pixman.i386 pulseaudio.i386
c) however, the backtraces are at least readable enough to see that both crashes
are in different places -- one is in flashplayer (which wouldn't be our
problem), but the other one is somewhere in firefox.
The first crash comes from flash-plugin, it's not a part of firefox but closed-source browser plugin. Please reopen if you find a reliable way how we can reproduce this issue.
