Gee, good hint! I didn't even have an idea I had anything pulseaudio-related installed, but there were libs in a package called "emul-linux-x86-soundlibs". I removed them and both WoW and winecfg start up properly. In winecfg I can't select any audio drivers though, and sound doesn't work. Does that mean I can't have sound? (I could live with that, though.) Thanks!
