Description sander.smid 2020-04-18 16:34:28 UTC

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 Could it be related that the source is no longer valid?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".

plasma-discover (5.18.5) using Qt 5.14.2

- What I was doing when the application crashed:

I've run installation of wine, then I went to settings and tried to remove flatpak source (while the install operation was still running).

New crash information added by DrKonqi

plasma-discover (5.18.5) using Qt 5.14.2

- What I was doing when the application crashed:

I removed Fedora's "testing" flatpak repository; then Discover crashed.
I opened again, repeated process, same result.
I was able to remove the "stable" repository with no errors.

I did a `flatpak remotes` to show whether they were both removed, and they were. But Discover still shows the testing/beta one.
I think the testing repository was removed along the stable automatically, but Discover didn't notice it for some reason.
