--- Comment #6 from Luzipher luziphermcleod@yahoo.ie --- More info: I tried again with juggler3d and it crashed first time upon exit. flurry also triggered the crash on exit. So I now suspect that antmaze isn't problematic - it is not starting a screensaver that causes the crash, but closing one. As I switched screensavers randomly in xscreensaver-demo, I just by chance clicked on antmaze when I had a problematic screensaver selected previously.
