Application: knotify4 (4.14.21)
KDE Platform Version: 4.14.22
Qt Version: 4.8.7
Operating System: Linux 4.6.5-300.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed: with every kde application: each time a notification should appear, knotify segfaults. Totally reproductible, does it every time. Running Fedora 24.

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
