-- Information about the crash:
- What I was doing when the application crashed:
Successfully connected to OpenVPN Connection and the widget appeared normally but on my second attemt to open the widget to disconnect from the connection Plasma crashed. This is happening every time since two days. Reboot does not help, running the updater also.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
