Bug ID: 451674
Summary: Crash after removing torrent after deleting its files
Product: ktorrent
Version: 21.12.3
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: joris.guis...@gmail.com
Reporter: groszdaniel...@gmail.com
Target Milestone: ---
Application: ktorrent (21.12.3)
Qt Version: 5.15.2
Frameworks Version: 5.92.0
Operating System: Linux 5.16.8-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.24.3 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
1. In a torrent that has finished downloading and was seeding, I converted the
files, thereby creating new files in the torrent's root directory.
2. I deleted all the original files in the torrent (except for the root
directory) outside KTorrent (with rm).
3. In the context menu of this torrent, I clicked Remove Torrent and Data.
A dialog popped up saying that it couldn't remove some file(s) (I expected
this, as I'd already removed the files). Then KTorrent crashed.
Note: I had used Remove Torrent and Data before on torrents in whose directory
I had created files; in these cases, KTorrent correctly removed the torrent's
files (but not those directories that contained files not belonging to the
torrent), and it didn't crash. IIRC I'd also used Remove Torrent and Data on
torrents in which I'd already removed some files (but I'm not sure about this,
and perhaps I hadn't removed all files in the torrent already).
The reporter is unsure if this crash is reproducible.
