Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
I right clicked the desktop and opened the add widget, then closed and opened the add panel and added a top panel, then I deleted the panel and when I tried to open the add widget again plasma crashed.

The crash does not seem to be reproducible.

-- Backtrace:
