[Bug 747126] [NEW] X crashes on first touchpad touch

 

Public bug reported:

Binary package hint: xserver-xorg-input-synaptics

After installing today's updates for natty and rebooted.
My X crashes every time I touch my touchpad immediatelly, and starts over with the gdm login screen.

The relevant (I think) part of the Xorg.0.log:
