Application: ktorrent (5.1.0)

Qt Version: 5.11.0
Frameworks Version: 5.46.0
Operating System: Linux 4.16.12-2-default x86_64
Distribution: "openSUSE Tumbleweed"

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

Added quickly several magnet links from the browser to  Ktorrent.
Crashes after a few moments when the load becomes to heavy.
Torrents still have to be confirmed manually for download. Only one magnet link made to that point.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28	  return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
