This doesn't explain the problem... - the import of the qtproxies module shouldn't fail so wrapping it in try/except shouldn't make any difference - if Python is no longer suppressing certain exceptions then you would expect to see new exceptions raised, not a segfault - if adding a call to str(), which shouldn't have any side effects, avoids the segfault then that implies a memory corruption problem.
