Description Rodney Baker 2011-09-10 07:41:56 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5) "release 7"
Qt Version: 4.7.3
Operating System: Linux 3.1.0-rc3-1-desktop-vk5ztv i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
Firefox caused a desktop hang while browsing facebook and watching flv videos. Switched to different tty via Alt-F1, logged in as root and issued init 3 followed by init 5. After kdm restarted and I logged in, Plasma immediately crashed and produced the attached backtrace.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Aborted
