Bug Description

Since about 2 weeks, my Xorg randomly crashes on my Thinkpad T410s (jumping back to login screen). Happens mainly during wakeup, but not only. I was running 12.04 for several weeks without this issue before.
Initially I thought this is the same as #1026777, but the segfault seems to occur in a different function.

Seeing that synaptics_drv.so is involved, I already tried to deactivate the touchpad (with synclient TouchpadOff=1), but didn't help. However the trackpoint is still on and I don't know if that's handled by the same driver.
