Seeing as you can auth via other methods, I don't think this is the case. You can probably find some info as to what's happening in the /var/log/gdm/* log files.

hrm... Well I'm able to log into other machines using my home directory, so I don't think it's the gnome session.  I've tried removing *all* of ~/.gnome2 but that didn't work either.

I do have some information in the .xsession-errors, but I can't tell if something is actually crashing or if something is just gracefully failing:
