Having the wrong library version can do that; I had a problem with an old build of vtwm.gamma, when newer libraries were installed but not the older ones that it needed, it would crash. However, it looks like the libraries I'm running with appear to match exactly the ones you're using and don't see the problem, so this probably doesn't help you much.
