Deleting BITMAPs results in segfault

Bug Description

The destructor of class GraphicSet (as well as GraphicSet::setGraphicSet) calls unLoadGraphics which deletes all BITMAPs. But this does not work — instead the game segfaults.

I worked around this problems by setting unused BITMAP*s to NULL. Since all BITMAP*s are (re)defined later this should not be required but it helped with the problem. I consider not to fix it and to live with this solution.
