Description Fabian 2022-01-14 21:44:13 UTC

Application: kcmshell5 (5.23.5)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.0-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I just imported an OpenVPN configuration file and wanted to activate it. After clicking the connect button in the plasma network menu I got a notification "Missing VPN plugin". I wanted to know more so I just clicked on the settings button in the notification right next to the close button and then nothing happened and I got a notification that it crashed.

- Custom settings of the application:
Just imported OpenVPN configuration and I'm apparently missing some VPN plugin. (I'll figure it out; not part of this report)

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault

Comment 1 Nate Graham 2022-01-21 00:55:40 UTC

Weird backtrace, looks like it's looping in something in Qt?

Comment 2 Ben Cooksley 2024-12-23 18:23:39 UTC

Bulk transfer as requested in T17796

Comment 3 Nate Graham 2025-05-15 19:58:14 UTC

Given that it looks like this might have been a Qt issue, can you see if it still happens in Plasma 6.3.5 or later with a newer Qt version? The latest is 6.9.

Thanks a lot!

Comment 4 Fabian 2025-05-18 12:42:38 UTC

Yes, it is working now with plasma 6.3.5 and Qt 6.9.0! Thanks
