Reliable crash at specific time (0.9-2943-g0e6b-25c)

In the save linked below, the game will CTD when the time passes 23:30.
This does not occur if I leave the area, for example by going downstairs. (This means that I am able to continue playing and this thread is posted for diagnostic reasons only.)
I’m guessing this is due to some timed event happening (item decaying or something) but then I know SFA about programming.
