I couldn't reproduce this bug using gnome-screenshot, so it was probably fixed
a while ago.

The crash was caused because the code didn't check the return value of
GlobalLock, and then tried to access lpbmih->biBitCount when lpbmih was NULL. I
added a NULL check anyway in wine-1.3.12-224-g356eaa1, so this crash shouldn't
recur.
