Bug 339398

Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-generic i686
Distribution: Ubuntu 14.04.1 LTS

The reporter indicates this bug may be a duplicate of or related to bug 310523.

Possible duplicates by query: bug 337197, bug 331121.

Reproducible: Always

Steps to Reproduce:
I installed the [QuickUrl widget](http://opendesktop.org/content/show.php?content=99815) using the "Get Hot New Stuff" feature.
The first time I tried to add it to the desktop, the widget told me it could not create the python script engine (or something to that effect), so I installed the plasma-scriptengine-python package.
This fixed that issue, but adding the widget to the desktop now causes Plasma to crash as the widget tries to configure itself.
