Sounds as if you have an invalid or corrupt grafport if you crash
in ClipRect(). Dont be too confident that the locality of the crash
is also the cause of the crash ! 

Did you do a DisposWindow() just before the ClipRect() ? Check 
thePort using the debugger and make sure everything is ok. Obviously
OpenPicture is only a symptom and not the problem, if you crash in
ClipRect(), before the OpenPicture().
