The Qt Documentation for 4.5.2 says that the arguments to QCoreApplication need to have lifetimes as long as the application object - so you shouldn't really use local variables.

I'm grappling with the same problem, and everything seems to work for me too. I would recommend being very careful at unload / exit time, however, since if you're using the event loop from another application and that event loop is stopped before your library is unloaded then all sorts of crashy nastiness can happen when you try to close() sockets and delete QObjects.
