Bug ID: 360711
Summary: Plasma crash after running new session accidentally
Product: plasmashell
Version: 5.5.95
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: m.sledzi...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.95)
Qt Version: 5.5.1
Frameworks Version: 5.20.0
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:
Locked my desktop and then accidentally chose the 'New session' option. After
that a new login screen was displayed, multimedia stopped (Amarok). Plasma
encountered a crash after switching back to locked session and unlocking it.
- Unusual behavior I noticed:
After switching back to my session of Plasma Amarok resumed playback but it was
laggy. After about 7-8 seconds of playing music disappeared for about a second
or two. After that music started playing again and then stopped again for a
number of times.
-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
