Application: knotify4 (4.0)

Distribution (Platform): Gentoo Packages

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

After upgrade 4.7.1 -> 4.7.2 Knotify crashes very often. Not after all notifications (ex. suspending indexing, desktop effects, email sending via kmail are ok). I noticed that almost all notifications from Akonadi causes Knotify to crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
