>Description:
I've noticed and in many experiments proved, that I can easily crash X with xterm and urxvt.

When I run any of
xterm -e mutt
xterm -e irssi
urxvtc -e mutt
urxvtc -e irssi

Xorg crashes (without coredump!!! How can that be?)
However I noticed /console-kit-daemon.core (perhaps it's console-kit crashing)

However X doesn't crash if I run
xterm -e sh -c mutt
xterm -e sh -c irssi
urxvtc -e sh -c mutt
urxvtc -e sh -c irssi

Pretty weird.
Logs didn't reveal anything.
