Don't know if this is related, but I had a problem exactly like that
except that it turned out to be related to the xscreensaver.  There's a
screensaver that is totally broke in Ubuntu (superquad something), that
no one seems to want to take ownership for.  If your screensaver is set
to random mode (and it appears it is by default), when this screensaver
comes on, or is selected for previewing, it will drop the gnome session
and log you out.  Once selected in the desktop it cannot be de-selected.
It must be dealt with manually.
