Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-23-generic i686
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
I clicked in the widget near the clock, click in change to online mode but it doesn't runs. I update recently the KDE plasma version to the last in kubuntu 15.10, previously this widget runs perfectly, but now when I click in configure chat account plasma crashes and self restart. The instant messaging application is unable to use, impossible to connect.

- Unusual behavior I noticed:
Previously it works, when I upgrade the new version of plasma kde it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
