Bug ID: 391374
Summary: Crash upon closing ktorrent
Product: ktorrent
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: joris.guis...@gmail.com
Reporter: k...@kolivas.org
Target Milestone: ---
Application: ktorrent (5.1.0)
Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.15.3-ck1+ x86_64
Distribution: Ubuntu 17.10
-- Information about the crash:
- What I was doing when the application crashed:
I had about a dozen torrents and I highlighted them all and deleted them (just
the torrents, not the associated files), but the lower window which showed
status of a torrent didn't disappear (coincidence?). I went to minimise
ktorrent by hitting the close window cross and it crashed.
-- Backtrace:
Application: KTorrent (ktorrent), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
