Bug 274934

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
KDE suspended to RAM, and whilst suspended power was changed to battery.  Whilst resuming, AC power was resumed (not sure of exact ordering, possible race ?).  When desktop resumed, plasma crash event was on the screen already.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
