In the second area of Volskygge; Volskygge Passages there is a double grate trapdoor in one of the rooms. Attempting to close the trap door after activation has crashed my game on every attempt.
Could be because the trap has too large an activation area? The trap activates when moving most places in the room it is situated in.

Sorry for the bother. This glitch has been fixed by the 1.1 update

This may still merit some work though; the trap will not reactivate autonomously after resetting
