Bug ID: 420259
Summary: Removing a Flatpak source crashes Discover.
Product: Discover
Version: 5.18.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: lei...@leinir.dk
Reporter: sander.s...@gmail.com
CC: aleix...@kde.org
Target Milestone: ---
Application: plasma-discover (5.18.4)
Qt Version: 5.14.2
Frameworks Version: 5.69.0
Operating System: Linux 5.6.4-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
In the Flatpak section of the Settings menu:
- Clicking the remove button for "GNOME Nightly Runtime - sdk.gnome.org".
- I can get the same crash by clicking the remove button for "Gnome Stable
Runtime - sdk.gnome.org"
Other sources (winepak) I can remove. Could it be related that the source is no
longer valid?
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".
