Description Ryan Swart 2017-02-16 04:19:49 UTC

Application: plasmashell (5.8.5)

Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.4.45-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Listening to Spotify whilst browsing the web

- Unusual behavior I noticed:
A prompt-window appeared stating that Spotify is using an invalid SSL certificate, clicking through to more details produced a normal window with overlapping text, at which point Plasma crashed.

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

Comment 1 Ola Røer Thorsen 2017-06-01 13:33:19 UTC

I'm getting this crash every 5 minutes or so now, if anyone need to test anything let me know.

Comment 2 Christoph Feck 2017-06-07 13:44:14 UTC

The crash is in the Qt libraries. If this is reproducible with Qt 5.9.0, please report a backtrace with debug symbols to Qt developers via https://bugreports.qt.io/

New crash information added by DrKonqi

plasmashell (5.18.5) using Qt 5.14.2

- What I was doing when the application crashed:

- Unusual behavior I noticed:

Playing spotify (spotify-client-1.1.26.501-1.fc31.x86_64) 
Get an error in relation to i.ytimg.com cert error, Click on More information - KDE Crashes, 
Manual Respawn 
kquitapp5 plasmashell
kstart5 plasmashell

Cert error will re-appear after a few moments, repeating above will crash KDE again, choosing to permenantly accept the certificate will remove alert and system will not crash.
