OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: joris.guis...@gmail.com
Reporter: sts33n...@gmail.com
Target Milestone: ---
Application: ktorrent (5.1.1)
Qt Version: 5.9.7
Frameworks Version: 5.55.0
Operating System: Linux 4.12.14-lp151.28.13-default x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I noticed that a torrent had finished downloading. I "stopped" it from the
right-click menu. (I did not remove the torrent from the list.) Then I hit
the "Quit" item in the "File" menu. KTorrent froze for about 20 seconds before
its window disappeared and the bug reporting window appeared.
-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
