Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

I also have (had?) this issue. I highly suspect that at least in my case the problem is that I installed amd's catalyst driver for my radeon card. Since catalyst doesn't support my card the xorg radeon driver is used.

I got the exact same stacktrace whenrunning glxinfo. I then uninstalled catalyst and can now run glxinfo. I don't know how to reproduce the error with gnomescreensaver so I can't verify that it is the same issue.
