Product: [Applications] Discover Reporter: irodrigue101
Component: discoverAssignee: Aleix Pol <aleixpol>
Status: RESOLVED DUPLICATE    
Severity: crash Keywords: drkonqi
Priority: NOR

Platform: Arch Linux   
OS: Linux   
Latest Commit: Version Fixed In:

Description irodrigue101 2018-07-06 01:43:20 UTC 
Application: plasma-discover (5.13.0)

Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.16.13-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I logged in, I saw and clicked on the notification for available package updates then, it instantly force-closed.

The necessary updates do show, as in, Discover shows an available update to ffmpeg and freedesktop.org Application Platform Version 1.6

Sadly once it finishes loading that panel showing me the package names, it closes automatically.

The crash can be reproduced every time.

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