Bug 387669

Application: ktorrent (5.0.1)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.9.56-desktop-1.mga6 x86_64
Distribution: "Mageia 6"

-- Information about the crash:
- What I was doing when the application crashed:

ktorrent crashed on exit, after pressing CTRL+Q.

A bunch of torrents were active but I don't know if that had anything to do with the crash.

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