Bug 280987

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
I had Kwallet open on a desktop and moved the app window to another desktop. I finished what I was working on and closed kwallet. On the desktop where I opened kwallet, there was still an entry in the task manager with Kwallet, but preview just showed a small box, no actual window, and when I right clicked it, Plasma crashed.

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