Xorg crashed with SIGABRT in OsAbort()

[Daniel Johannes Knob Kerekgyarto]

Appears randomly and seems to only happen with intel based graphics. (I have access to two identical thinkpads, one with nvidia and one with intel. same setup on both, same os, same specs. only appears on intel) Fixes itself on reboot. Possible connection with dualboot system with Windows 7 Pro. Happens more often after rebooting from Windows and booting into Ubuntu.
