Bug 358625

Application: kalarm (2.11.3-5ak)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160121) (x86_64)"

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

I had Kalarm in systray and when I clicked on its icon, I got segfault.
Now when I want to reproduce it, kalarm won't create icon in systray.

-- Backtrace:
Application: KAlarm (kalarm), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
