Bug ID: 393601
Summary: KTorrent crashes when port changes
Product: ktorrent
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: joris.guis...@gmail.com
Reporter: mayeul.can...@live.fr
Target Milestone: ---
Application: ktorrent (5.1.0)
Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
* I opened KTorrent (a few torrents were there, downloading)
* I opened the settings window
* I changed the port KTorrent was listening on
* I hit "Apply"
* KTorrent crashed.
I can always reproduce this bug. The settings seem to be remembered when I
restart KTorrent. DHT is enabled, if that matters at all.
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".
