Sorry about that. If you try to encode the "magnet://" string to base64, you'll get: $ echo "magnet:?xt=urn:btih:f9aadd61ca33fd1d0c47296140e88faf1f3dd2a2" \ | base64 -w0 ; echo bWFnbmV0Oj94dD11cm46YnRpaDpmOWFhZGQ2MWNhMzNmZDFkMGM0NzI5NjE0MGU4OGZhZjFmM2RkMmEyCg== Which means your encoded string (the one starting with "QUF") is not identical to the encoded "magnet://" string. As such, I'm closing this bug. If this is still an issue, discussion can continue by replying to this thread. -assaf From unknown Fri Aug 15 15:32:19 2025 Received: (at fakecontrol) by fakecontrolmessage; To: internal_control@debbugs.gnu.org From: Debbugs Internal Request Subject: Internal Control Message-Id: bug archived.
