Description Vincent Reydet 2016-11-14 11:20:13 UTC

Application: plasmashell (5.8.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was using firefox, doing nothing special with KDE/Plasma.

I also noticed a loss of one of my wallpaper background. I use 3 screens and I'm having issues keeping my screens configurations: I always loose my wallpaper background or configuration (often it's just shuffled between screens) when plasma crash. The shuffle also happen at boot.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Comment 1 Michele Bertuccioli 2017-03-20 08:53:19 UTC

Same problem here. The stacktrace that I can provide is considered unusefull, but the problem is here from kde 5.7.x

Random crash of plasma, apparently related to an application switch.
I'm on one screen system.

Application: Plasma (plasmashell), signal: Segmentation fault

Plasmashell crash

Comment 3 Hugo 2018-06-02 18:05:35 UTC

My crash was in Debian 9 (Testing).

Comment 4 Christoph Feck 2018-12-21 00:00:11 UTC
