Brecht, could you please check this one? From first glance seems rev50995 is the candidate for a culptrit, not sure tho -- everything works fine on gtx560ti.

Also seems 580 is sm_20, not sm_30.

It's possible that it's 50995, but that code only runs when the "Sample as Lamp" option is enabled for the world, which is not enabled by default. Does this crash happen with any the default cube, or only with a specific .blend file? In case of the latter, please attach a file that crashes.

From the forum post it seems this is related to sample as lamp, which was fixed now.
