Bug 255236

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

After an update, some of my widgets weren't displaying anymore, even though the configuration dialogue claimed that they were still running.

I deleted ~/.kde/share/config/plasma-desktop-appletsrc and restarted, which defaulted everything.  I then started adding widgets again (two folder views, an analog clock and a weather widget).

While resizing the weather widget, Plasma crashed, apparently saving which widgets I had been running, but not their positions or sizes.

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