Bug ID: 364599
Summary: Crash when desktop left idle
Product: plasmashell
Version: 5.5.5
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: krothw...@espial.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
(Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.6-gentoo x86_64
Distribution (Platform): Gentoo Packages
-- Information about the crash:
- What I was doing when the application crashed:
Session was left idle. Various applications were left open (thunderbird,
skype, putty, konsole, slickedit, dolphin), but it's not certain this matters
when reproducing the bug - plasmashell seems to crash randomly, rather than due
to any action performed.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
