I just started getting this error preceded by another from gnome-session. The screen freezes and turns into either bands of yellow or green.
It only occurs upon ending an X session and really strange part is that it only occurs with one user. I've tried to recreate the problem as root without success and created a new user and the X sessions for both exit normally. The system functions fine otherwise but I cannot log into a tty until I reboot via ssh.
gnome-session: GLib-CRITICAL: g_key_file_load_from_dirs: assertion `!g_path_is_absolute (file)' failed

I forgot to mention that the keyboard is unusable as well.
However, if I log in via ssh and type the following command:
/usr/bin/startx --localhost :0.0
the screen clears and the terminal and keyboard are responsive once again.
