There is another bug report about WoW crashing here:
http://bugs.winehq.org/show_bug.cgi?id=19719
Their solution was to remove <WoWGameDir>\Data\patch-a.mpg. Maybe this helps for you too.
Yeah I saw that solution. And I tried it out. But that "patch-a.mpg" file didn't even exist in the specified directory...Nor in any other directory. So I couldn't remove it since it wasn't there. =(
