Killing winbind resolves the problem, but that is not a usable solution for most of us.

I think I've managed to find the cause of this: winbind!

This was my nsswitch.conf file:

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         compat winbind
group:          compat winbind
shadow:         compat

hosts:          files wins mdns4_minimal [NOTFOUND=return] dns mdns4
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files


I removed all references to winbind from this file and did an 'aptitude remove winbind'

Firefox is now stable, tried re-installing flash and re-activating my
plugins, no crashes since!

Someone else with a 64-bit machine should now try to re-create this if
possible and then hopefully we will have a definitive way to reproduce
this.

Is it a firefox bug or a winbind bug? Should a seperate bug be raised as
a winbind issue?

You received this bug notification because you are a direct subscriber

Status in “firefox-3.0” source package in Ubuntu: Incomplete

Bug description:
Basically the same stacktrace on most pages.  Is NOT tied to Flash (have tried w Flash installed and removed).  Not usable, using Firefox under Wine as workaround (ick!)
