	I found it quite easy to crash the game using the blindfold.

	Just get into wizard mode and teleport to hell with the blindfold on.

	Then start to search the level. You should get the message

	" At get null a 00 00 " which will soon be followed by a segmentation

	fault.  I think saving the game prevents the crash.  If you don't

	get the "at gets null" message start moving up levels with the 

	blindfold on. It will happen sooner or later. Could someone post

	a patch for this?
