OK, you are saying that this most likely happens in the bitmap/RLE
display function. (NB: I cannot reproduce the crash on DJGPP).

I would suggest you put lots of al_trace() calls inside 
allegro/tools/plugins/datimage.c; maybe you can figure out what is going
wrong. Also, if you comment out the call to actually draw the sprite or
bitmap onto the screen (not the rest of the view function, just the
specific line), then does the grabber continue without crashing? If so,
then you have narrowed down the culprit.
