This seems to have been fixed upstream in the transmission-client crate:

https://gitlab.gnome.org/haecker-felix/transmission-client/-/commit/29e109cd2ebd653683b48d343a885564e3eb3bf7

Might be related to updating to a transmission beta release rather late
in the freeze, but I haven't found the daemon-side change yet..

In any case a targeted cherry-pick of that commit above to
rust-transmission-client followed by a rebuild of fragments should fix
the issue!
