Bug ID: 360641
Summary: Plasma randomly crashes after inactivity
Product: plasmashell
Version: 5.5.4
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kde....@xapienz.ru
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.4)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-10-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)
-- Information about the crash:
After some period of inactivity (usually when I go to work or sleep) plasma
crashes several times (3-5 times per 8 hours).
Seems to be some problem with monitors.
I have a laptop with HDMI monitor connected, laptop screen is disabled in KDE
Settings.
The stacktrace looks similar to bug #350994, but I don't have to do anything
special to reproduce it.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
