Desktop and XSever completely unresponsive after running command

[pik]

Screen / XServer become completely response after running sudo gparted and the system requires a hard-reboot.

Try next time to jump in another tty (ctrl+alt+fN) and catch logs.
Did you configure sudo with visudo to running graphical apps? Is that bug also appears with gksu or kdesu?

This is uniquely related to the way gmrun calls the command. Also I don't think I can get to another terminal - but I can strace or put some debugging statements into the gmrun code to see what's happening.

Are you unable to reproduce this btw?
