Bug ID: 496725
Summary: Crash on closing KTorrent
Classification: Applications
Product: ktorrent
Version: 23.08.5
Platform: Kubuntu
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: joris.guis...@gmail.com
Reporter: andy...@mail.ru
Target Milestone: ---
Application: ktorrent (23.08.5)
Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-49-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.1 LTS
DrKonqi: 5.27.11 [KCrashBackend]
-- Information about the crash:
KTorrent crashed when I right-clicked on its icon in the task bar and selected
Quit. There was code compilation running on all cores in the background, which
made KTorrent nearly unresponsive. Most other applications were responsive at
the time, so the problem was specific to KTorrent. There were several torrents
seeding and downloading when I clicked Quit.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: KTorrent (ktorrent), signal: Aborted
