Bug 370739

Application: ktorrent (5.0.1)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.7.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
See title. No matter how I add the magnet link. It will not be added and KTorrent crashes.

KTorrent also crashes shortly after a torrent file is added and started downloading.

The crash can be reproduced every time.

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