Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-19-generic x86_64
Distribution: Ubuntu 15.10

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

Complete KDE panel (possibly even window manager) crashed when trying to add instant messaging account. It happens every time.

To reproduce:
Click on instant messaging symbol -> No accounts are configured yet -> Click on configure now -> Select an existing Google Mail account -> Configure ... -> crash

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
