Probaly two issues:
 - the Group::move_hande() was seriously flawed (transformation is one
   of the new features after 0.97.x). I've just pushed a better
   implementation to master [1]
 - the transformed group was really small so select all had to work on
   a huge diagram. There was an issue with the GDK renderer trying to
   allocate huge internal pixmaps, which than failed [2]. There might
   be other issues like that.

Dia is generally build with high warning level. But I seriously doubt the 
crash has anything to do with float vs. int.

Yes, certainly. I don't think it has anything to do with your patch.
But you should try yourself by trying to reproduce the crash without
it. Please build Dia with --enable-debug=yes so that you can provide stack 
traces of your crashes.

Thanks,
