qBittorrent: SIGSEGV crash when resuming any torrent #56995
Description
Is this a new report?
Yes
System Info
Void 6.12.43_1 x86_64 AuthenticAMD notuptodate rrrmFFFFFFFF
Package(s) Affected
qbittorrent-5.1.2_1, libtorrent-rasterbar-2.0.10_4
Does a report exist for this bug with the project's home (upstream) and/or another distro?
qbittorrent/qBittorrent#23206
qbittorrent/qBittorrent#23215
Note that a qBittorrent team member (xavier2k6) has recommended that I request libtorrent-rasterbar to be updated to version 2.0.11 in the Void repos.
Expected behaviour
Selecting a pasued/stopped torrent and resuming it with Ctrl+S while the session is unpaused (Ctrl+Shift+S) should resume the torrent without issue. Same goes for resuming a session with resumed torrents.
Actual behaviour
qBittorrent crashes whenever I attempt to resume any torrent. When run in a terminal, the crash produces one of the two following outputs:

Steps to reproduce
- Ensuring Tools --> Preferences --> Advanced --> "Start BitTorrent session in a paused state" is checked, start qBittorrent in a terminal (
$ qbittorrent). The qBittorrent window should appear but with the session paused ("[PAUSED]" appears in the window title) like expected. - Resume any single torrent by clicking it and then either pressing the Start button or pressing Ctrl+S.
- Try resuming the session either by either via Edit --> Resume Session or Ctrl+Shift+S.
Alternatively, you can first ensure all torrents are stopped, resume the session, and then try resuming any individual torrent. It will cause the same crash.
