Public bug reported: Whenever as root in a terminal, I start 'gvim', the whole windows system crashes and the user find himself on the gdm login screen. Windowing session has been lost.
It only occurs with gvim. I tried xterm, terminator and gthumb as root and these graphical application do not cause the crash.
