-- Information about the crash:
Steps to reproduce

1.) Add new (default) Panel
2.) Activate Edit mode ("Alt+D, E") via right-click menu of the desktop
3.) Activate Editing of Desktop and Panels (translated from German, sorry)
4.) Remove any panel

Actual Result:
Plasma crashes, the panel is not removed. Note: The Edit mode (Alt+D, E) will not show the option for editing desktops and panels right now, you'd have to add another panel to enter it again

Expected Result:
Panel is removed.

The crash can be reproduced every time.
