Description Kyle 2011-06-30 04:57:37 UTC

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 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: I was using the XBMC Media Center, watching Pokemon *Not ashamed* off of the Youtube Video Add-On, when after I closed it out, KWin crashed. Not a surprise though, it's very resource intensive, although more lightweight than Windows Media Center, and when I used it on Arch Linux it caused my entire laptop to crash, causing me to kill Xorg. 

TL;DR: Was using XBMC to watch Youtube videos and upon exitting it crashed.

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

Comment 1 Thomas Lübking 2011-06-30 10:56:27 UTC

driver bug, to workaround either really suspend compositing before going
fullscreen (shift+alt+f12) or disable suspension for fullscreen window (yes,
sounds weird ;-) in "kcmshell4 kwincompositing" (3rd tab)
