Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Ubuntu 12.10

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

I downloaded http://opendesktop.org/content/download.php?content=114504&id=1&tan=90998747&PHPSESSID=2d2698c87616a93b300b20752eb94c15

and attempted to install Widget from local file and then plasma crashed.

The crash can be reproduced some of the time.
