Bug ID: 359756
Summary: Crash that unlocks the session
Product: plasmashell
Version: 5.5.4
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: d.d.huis...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.4)
Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
I turned back on my screens after some AFK time.
The session was manualy locked. I just had normal applications open when a
session is locked. Firefox, Thunderbird, Kdevelop and a torrentclient.
- Unusual behavior I noticed:
At turning back on the screens I had seen a short flash of the lock screen just
before the session was auto unlocked the debug screen was shown.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
