Application: ktorrent (5.1.0)

Qt Version: 5.10.0
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: Selecting "Quit" in the file menu whilst in the "Plugins" screen crashes the application. Closing it using the "X" on top of the window, just closes the program without crashing. Tried multiple times; crashes each time via the "quit" option in the file menu.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
