New crash information added by DrKonqi

kwin (4.6.2 (4.6.2)) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed: reenabling and modifying desktop settings.

Comment 2 Thomas Lübking 2011-06-15 09:00:03 UTC

fixed in 4.6.3  - set the scale method to "smooth" to workaround for 4.6.2 ("kcmshell4 kwincompositing", 3rd tab)
