Description Dr. Dwight Scott Miller 2015-11-23 15:51:50 UTC
Application: knotify4 (4.14.6)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-29-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
looking at kalarm, receiving email, using espeak, trying to enter the bug report ... about thee only thing that does *NOT* cause random crashing of knotify is the "configure notifications" dialog in kontact

- Unusual behavior I noticed:
espeak under kalarm sounds as if the speaker were talking through a highspeed fan or had a mouth full of cicadas

The crash can be reproduced sometimes.

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