[Pkg-kde-extras] Bug#949839: KTorrent sends invalid requests to webseeding URLs

[Nicolás Alvarez]

Package: libkf5torrent6
Version: 2.1-2
Severity: important
Control: affects -1 + ktorrent
Control: fixed -1 2.1.1-1

KTorrent in Debian Buster sends invalid HTTP requests to webseeds:

GET /path/to/file.ext?HTTP/1.1

There is a question mark instead of a space. This makes most (all?) web
servers respond with 400 Invalid Request. As a result, it's not possible
to download from webseeds in this KTorrent version.

This bug has been fixed upstream:
https://cgit.kde.org/libktorrent.git/commit/?id=03c1144efc5fc9ddfb7322defdc28153a4e010c2

This fix is present in libktorrent 2.1.1, which is currently packaged in
Debian testing (bullseye), but I believe it may be justified to backport
a patch to stable.
