Public bug reported:
On Ubuntu 15.10 I get crashes, when I open a new window in an already
started application. It happens irregularely, but I can force the crash
if I open several new message windows in thunderbird. But it also
happens in other applilcations, for example a new terminal window.
This is the output during the crash in /var/log/Xorg.0.log
