Bug ID: 358163
Summary: plasma crashes after opening audio volume settings
from systray
Product: plasmashell
Version: 5.4.3
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: leon...@lausen.nl
CC: bhus...@gmail.com, plasma-b...@kde.org
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".
