While trying to create a trace of this problem with firefox -g, I encountered another bug where firefox just hangs and stops responding. I don't know how related these are but I would guess they may be related, I'm using kubuntu feisty that is fully updated. I'll try to get another stack trace of the problem where firefox window closes with a segfault (the one below is firefox hanging), I've encountered the firefox close problem but I'm waiting for it to go off again so I can give you a back trace.
