Bug#478836: The substrate screensaver has the same problem

["Sander Marechal" <s.marechal@jejik.com>]

Hello, 

It looks like the "substrate" screensaver in xscreensaver has the same 
problem. It runs for about 10-20 seconds and then it freezes my entire 
system. At first I could go to the console with Ctrl+Alt+F1 and kill 
substrate from there, but later on even that would not work. I had to raise 
a bunch of skinny elephants to get my system back under control. 

As the bug submitter mentioned, everything works like a charm under 
metacity.
