Bug#818437: Nearly same behaviour

[surf]

I am experiencing the same behaviour both with VGA and HDMI.

The only difference is that my system freezes few seconds after
switching to tty1.

My /var/log/messages displays this two lines right before the freeze:
Mar 18 12:06:38  kernel: [11136.909382] traps: gnome-shell[2859] trap
int3 ip:7f9d31adb87b sp:7ffe42e5e8f0 error:0
Mar 18 12:06:42  kernel: [11140.123641] gnome-shell[4195]: segfault at

libmutter.so.0.0.0[7fde5b3b2000+fc000]

Thanks.
