Application: kwin (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-9-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

From a fresh install, I had opened the screen saver application and selected "Solar Winds (GL)".
I clicked the test button, and the screen saver ran normally.
Clicking again (to end the test), KWin repored a crash.

As there was no actual hibernation involved and the issue does not manifest with the current ("blank screen") screen saver, I feel that this is something related to at least some of the screen savers, rather than to hibernation (or a combination of the two).

- Custom settings of the application:

-- desktop effects enabled
-- current screen saver is "blank screen" and does not cause problem
-- test of "Solar Winds (GL)" causes problem

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
