Please install xulruner and firefox debug packages and try to catch it again.
Let me add slightly more verbiage which amounts to basically the same what
Martin was saying:
Please install firefox-debuginfo; in order to do this you have to run
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
(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.
Changing version to '9' as part of upcoming Fedora 9 GA.

Are you sure gdb didn't complain about missing debuginfo packages and it didn't
suggested using debuginfo-install for installing them?
Can't reproduce, please reopen if you find a reliable way how we can investigate this issue...
