Sorry for the late reply. I am running in UNE session most of the time. Once
in a while I log into to gnome session for 5 min or so. One problem I
noticed is that once I log on to gnome session, the old style menu bar comes
along the unity bar. I have to remove the conf files to get it disappear.
This need to be somehow taken care of as well.

But I still have not found any reason to link the gnome-session log ons and
the crashes.

It is our duty to help ubuntu make better. We should be thanking you guys
left and right. I am a long time debian user, I still prefer to use debian,
but I am using ubuntu now so that I can try to do something to the
community.
