Description Stanley Mangapi 2021-05-13 06:54:05 UTC 
Application: ktorrent (5.1.1)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 5.6.0-2-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
Ktorrent crush when closed from System Tray. It happens when closing the app from system tray while the main application is not closed.

But if main app is closed, then exiting the app permanently from system tray does not raise any error

- Unusual behavior I noticed:

- Custom settings of the application:

The crash can be reproduced every time.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
