Bug#677397: gnome-session: Gnome crashes when USB device plugged

[Santhosh Thottingal]

Package: gnome-session
Severity: normal

When the laptop is connected any USB device like USB mouse or external
keyboard, the gdm3 does not start. It tries to start multiple times.
But fails.
When the gnome3 desktop is running, if any USB device is plugged,
gnome3 crashes , tries to restart gdm3 again , fails.
Without USB devices plugged everything works fine.

Let me know any additional information I need to give.
Version of gnome I use is 3.4
