Hmm. That backtrace is lacking, which seems like bug 34813, which was supposed to be fixed for Wine 1.7.8. :(
Or maybe you're using a build that's been stripped of its debugging symbols or uses DWARF 2 debugging symbols instead of "stabs" symbols. If you can obtain or build a version of Wine that has stabs debugging symbols intact, that may produce a better backtrace.
