Vegastrike has been crashing on me, but I had suspected that this might be
due to older hardware or open source drivers having an issue. A bug
has been filed (
https://bugzilla.redhat.com/show_bug.cgi?id=707165), but
I am wondering of vegastrike is working for anyone in either F15 or
rawhide. (Rawhide has a later bugfix release of the ogre library.)
