Changing the camera view makes it work... leaving it zoomed in crashes it on my computer.

Did you follow the steps exactly or did you orbit / zoom before knife projecting?

No, I do not change camera view.
I changed view to show a result and took a snapshot.

I am going to try on different drivers and see if that makes a difference

Drivers 332.21 doesnt crash with a gtx590 (different computer, pretty similar setup)

I could reproduce the bug.
It seems that the problem is in function bmesh_disk_facevert_count.
Within it, the bmesh_disk_edge_next(e_iter, v) is returning NULL when it should not.
Now just need to know why.
