Bug#792524: desktop crash

[Daniel Pocock]

Package: gnome-session
Version: 3.14.0-2
Severity: serious

My whole desktop crashed and went back to the login screen.  It happened
when I right clicked a link in a web site I was viewing with iceweasel.

This type of thing wasn't happening with wheezy / GNOME classic.

The log shows a message from gnome-session about 1 second before a crash
in the X server.
