I have the same problem with Mozilla since I switched from RELENG_5 to
RELENG_6. I've rebuilt all my ports completely but it keeps crashing
from time to time. This can happen after hours or after a few minutes,
mostly when klicking a link.

I think it's related to FreeBSD 6 as I don't see this problem on 5.x
machines with similar setup. I have linuxpluginwrapper installed on all
machines.

I would like to make a PR but I'm not sure how to collect some useful
information from the mozilla-bin.core. I start gdb with:

  $ gdb /usr/X11R6/lib/mozilla/mozilla-bin mozilla-bin.core

I obviously don't have a clue about how to use gdb, what can I do next?

tnx,
