Bug 432993

Application: ktorrent (20.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.8.0-36-generic x86_64
Windowing System: X11
Drkonqi Version: 5.20.90
Distribution: Ubuntu Hirsute Hippo (development branch)

-- Information about the crash:
- What I was doing when the application crashed:I was downloading torrents, I finished downloading one of them and closed the application correctly. Then I rebooted the system from the menu and when trying to open Ktorrent it would continually close showing unexpected shutdown error messages. When clicking on the option to reopen the application, the closing error repeats itself constantly, to the point that it is impossible to use the application directly

- Unusual behavior I noticed:I noticed some strange behavior when clicking on the torrent to download since I accidentally clicked it and Dolphin opened. It didn't seem like Ktorrent's usual behavior.

- Custom settings of the application:The number of seeds has been modified to 1024, the number of global connections to 1024, use DHT, the option to sow after finishing the download and use of microUTP is disabled

The crash can be reproduced every time.

-- Backtrace:
