Bug#424516: xserver-xorg: xserver segfault when closing keyjnote using nv driver
> Might be related to #420860 (but the whole stack is not exactely the
> same). To get a nice backtrace, you should install xserver-xorg-core-dbg
> and attach a gdb through ssh before the crash:
Got a better one:
Attaching to program: /usr/bin/Xorg, process 11216
