Description John O'Shaughnessy 2015-10-25 01:59:56 UTC

Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.2.1-1-desktop x86_64
Distribution: "openSUSE Tumbleweed (20151017) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
saving audio configuration
- Unusual behavior I noticed:
this happens when adjusting settings on the system or in any application. plasma usually recovers. this incessant recurrence of dialogues repporting a segmentation fault is irritating.

The crash can be reproduced every time.

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