Bug ID: 362745
Summary: Random plasmashell crash
Product: plasmashell
Version: 5.6.3
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: cogre...@yahoo.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.6.3)
Qt Version: 5.6.0
Frameworks Version: 5.21.0
Operating System: Linux 4.5.2-302.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"
-- Information about the crash:
What I was doing when the application crashed:
Absolutely nothing. What I have found is that plasmashell will crash whenever
the computer is left alone for an extended period of time. No idea what the
length of time is (sorry, not watching the clock :) ). Sometimes the screen is
locked - when the screen is locked it doesn't matter whether it's the built-in
(KDE) or another screen locker (XScreenSaver) program is used.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
