Bug 241986

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

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

Had a window marked with a generic X11 icon which I had taken to be a window relating to DAVmail which I thought I had killed, but on closing it I found it killed my plasma-desktop process with a SEGV.

I've selected a bug which appears to be the same but the backtraces seem to differ significantly.

I wonder if the data engine mentioned is related to either the weather backdrop or the weather station widget I am running ?

This is KDE 4.5.0 beta 2 with the packages from the Kubuntu PPA installed (upgraded this morning):

plasma-desktop:
  Installed: 4:4.4.85-0ubuntu1~lucid1~ppa4
