The crash occurs when saving. I remember that Black & White makes these small,
DXT compressed thumbnails of a screenshot taken when saving for viewing in the
citadel. It, however, makes a screenshot of only part of the screen, for which
it uses blitting. 
It just so happens the DDBltFx struct is not fully implemented in Wine ddraw,
which I'm pretty sure causes the segmentation fault. Look here:

When I'm less occupied with college, I'll look further into this bug. Though I
hope it's quashed by then.
