Backtrace from firefox

I have just tried this on another machine and reproduced the results. This was
again updating from the previous rpm, checking for both extensions and themes
(and updating the mostly crystal theme). When I quit firefox, the backtrace appears.

I just got exactly the same firefox-1.5.0.7-1.fc5, again on exit after updating
some extensions (flashblock, cookie button, live http headers):

Not easily reproducible, as all of my extensions are now up to date.

I've since upgraded to firefox-1.5.0.9-1.fc5. Will see if it happens again next
time my extensions need updating.

Please check if it happens again. And attach a bactrace from gdb, how-to is here
- http://people.redhat.com/stransky/mozilla/

Fedora Core 5 is no longer supported, could you please reproduce this with the
updated version of the currently supported distribution (Fedora Core 6, or
Fedora 7, or Rawhide)? If this issue turns out to still be reproducible, please
let us know in this bug report.  If after a month's time we have not heard back
from you, we will have to close this bug as CANTFIX.

Setting status to NEEDINFO, and awaiting information from the reporter.

Thanks in advance.

I've not been able to reproduce this bug using firefox 2.0, so I'll close the bug.
