Description Michał 2024-06-28 20:44:20 UTC

Application: ktorrent (24.05.1)

Qt Version: 6.7.2
Frameworks Version: 6.3.0
Operating System: Linux 6.9.6-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 6.1.0 [CoredumpBackend]

-- Information about the crash:
I'm using the word unloading because it causes crashes both when being disabled and when exiting the app.
When disabled KTorrent closes normally.
The attached backtrace is from a crash during exiting.

The crash can be reproduced every time.

-- Backtrace (Reduced):

New crash information added by DrKonqi

DrKonqi auto-attaching complete backtrace.

Comment 2 Michał 2024-06-28 20:53:59 UTC

After reporting this I encountered a crash with the plugin disabled. When I looked at the backtrace it looked like the crash was caused by a different component. I need to look into this more.
