Issue here is that remote connection will use OpenGL 1.1. There was a call here that would free VBOs always without a check, however the VBO free function pointer is NULL on such contexts causing a crash. This must have been causing some of the crashes with old contexts. While I think supporting those systems is not such a good idea in general, they can have a few more moments of support I guess. Things might be better now for systems using OGL 1.1 though there are still things that could be done better here - for instance going to dyntopo can crash immediately because we don't have a fallback implementation there. It might be worth reimplementing sculpting with vertex arrays for the legacy case too, but I guess if we move on to OpenGL 2.1 soon this is a bit of a wasted effort.
