Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I have reproduced this bug with all sorts of popups that can  be grabbed and put on the desktop... once they are a plasmawidget by themselves and i move them, plasma crashes... this particular crash has been produced by clicking on the battery status, dragging the popup onto the desktop and then moving it there

The crash can be reproduced every time.

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