Firefox segfaults on gnome, not kde, only from XDMCP

In case anyone else is interested in this very odd situation:
https://launchpad.net/distros/ubuntu/+source/gtk+2.0/+bug/61303
User testing suggests the problem is related to gnome's default
profile for Ubuntu 6.06. When a user changes away from 'Human' (eg.,
to 'LegacyHuman'), the problem goes away.
Anyhow, I mostly guessed as to where to file the bug. Might or might
not be upstream...
I'm interested to know if it's replicable... I'm half surprised it
hasn't shown up elsewhere.
