xdg-mime not behaving

Question

I am trying to set the default application for magnet links using:

~ $ xdg-mime default deluge.desktop x-scheme-handler/magnet

Checking this with grep -i deluge ~/.local/share/applications/* yeilds:

 /home/manko/.local/share/applications/mimeapps.list:x-scheme-handler/magnet=deluge.desktop
 /home/manko/.local/share/applications/mimeapps.list:application/x-bittorrent=deluge.desktop

i.e. it should have worked right?!? c.f:

~ $ xdg-mime query default x-scheme-handler/magnet
deluge.desktop

However when I run xdg-open magnet:?xt=urn:btih:6fa3fa92... chromium fires up!

I'm stumped.

Answer 1

I ended up using this patch for xdg-open, which just hardcodes deluge.

Hack central but does the job, and at least taught me that xdg-open is a script which I can play with.
