Description Leonard Lausen 2016-01-18 13:44:00 UTC 
Application: plasmashell (5.4.3)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-23-generic x86_64
Distribution: Netrunner 17

-- Information about the crash:
Using netrunner 17 (upgraded from 16) I can reliably crash plasma by right clicking on the audio / volume systray icon and selecting the "Audio Volume Setting". The settings window appears (but no content is shown). After closing the window plasma crashes every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 2 Marco Martin 2016-02-11 09:35:32 UTC 
can't seem reproducible here.
does this still happen with Qt 5.5 and newer workspace/framwork?
Comment 3 Leonard Lausen 2016-02-11 11:10:36 UTC 
It was solved for me (partially) with 5.5 (or the current packages in netrunner). The desktop still crashes sometimes in relation to some settings dialogues (bluetooth / sound related), but not any more every time. Still trying to get a good backtrace to file a bug.

Regards
