Bug 321192

Application: plasma-desktop (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.8.0-25-generic x86_64
Distribution: Ubuntu 13.04

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

Normally I use Choqok for twitter, for a few days that has stopped working. From searching online, it appears that Twitter turned off API V1.0 and only allows connections through API V1.1. Since Choqok doesn't currently support API v1.1, I went looking for something else. Found the KDE Widget and added it to the desktop. Configured it ok, no errors. It shows that it attempts to update the timeline but I either don't see anything or don't know where to look. Maybe this widget doesn't support API v1.1 either? Anyway, while looking around, in and out of settings/config for the widget, I right clicked on the widget and the whole desktop went black for about 5 seconds. Then it came back and gave me the crashed message. I had right clicked once before that without issue, but this time it crashed.

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