No, broken driver installation - no OpenGL application will work. It seems the MESA GL library is used, but probably the fglrx driver is loaded (check /var/log/Xorg.0.log) *** This bug has been marked as a duplicate of bug 213182 ***
Unlike bug 213182 though, this only seems to have happened once. It didn't happen when I restarted (after installing some updates). If it was a driver problem wouldn't it happen every time?
I'd say that "installing some updates" could have easily fixed it. As mentioned, it is *not* a driver bug, but a broken driver installation. Afaiu fglrx simply needs to run a script to relink some files.
