ktorrent (5.1.0) using Qt 5.9.1

- What I was doing when the application crashed:

I selected File->Quit in the main window menu and Ktorrent crashed. In my case, this was the first time Ktorrent was running after reboot. Ktorrent was started automatically on the system startup.

ktorrent (5.1.0) using Qt 5.10.1

- What I was doing when the application crashed:
Closing KTorrent with Ctrl-Q crashed the app after a few seconds.

I'm on ArchLinux but I compiled KTorrent from sources with "-DCMAKE_BUILD_TYPE=RelWithDebInfo" to get a better trace.
