Bug 355449

Application: systemsettings5 (5.4.1)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-18-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
Previously added one google hangouts account. Opened settings after restart to fix some details --> plasma crash. This is possibly a duplicate report but I submit it to add information. I was not able to use the reporting tool to mark it as a possible duplicate.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemoppsett (systemsettings5), signal: Segmentation fault
