This doesn't look like a gnome-session issue. It looks like Xorg died:
gnome-settings-daemon: Fatal IO error 104 (Connection reset by peer) on X
server :0.0.
gnome-session: Fatal IO error 11 (Resource temporarily unavailable) on X server
:0.0.
-----
The application 'gnome-panel' lost its connection to the display :0.0;
most likely the X server was shut down or you killed/destroyed
the application.
XIO: fatal IO error 0 (Success) on X server ":0.0"
after 1159 requests (1152 known processed) with 0 events
remaining.
No protocol specified
Window manager error: Unable to open X display :0.0
** Package changed: gnome-session (Ubuntu) => xorg-server (Ubuntu)
