Please run apport-collect 900111 to attach more information. It would

installed?

Here is your chance to get back into X development! :) Seriously, having
the hardware at hand is a huge advantage. Meanwhile I have found a
similar bug report here: http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=546836 where it appears to be a regression since
