The screensaver crashed for me after it activated during installation of the nvidia-current driver. I moved the mouse, then clicked the right-click to deactivate the screensaver. When it did not de-activate, I hit the shift key on the keyboard. After inputting the password to unlock the screen, the desktop appeared with an apport message about this crash.

Thank you very much for having reported this crash and the attached documents. There should be enough information for the developers to begin working to resolve this issue, so I am marking it confirmed.

[Chris Coulson (chrisccoulson)]

This is a bug in the proprietary nvidia drivers, and the helper crashing doesn't have any effect on the ability of the screensaver to function

[Charlie Kravetz (cjkgeek)]

I have to beg to differ on this. The driver that should have been is use at the time of the crash is "nv" from the repositories. Until I reboot, the nvidia-current(nvidia-graphics-driver-190) driver is not in use.

[Chris Coulson (chrisccoulson)]

The top of the stack is the proprietary nvidia libGL.so. You don't need to reboot for that. This is a common crasher in some atexit() handler that the nvidia library registers, and we get lots of duplicates of the issue. There's nothing we can do about it though
