Actually there are two alternatives:

1) Chrome is broken and only obeys Gnome settings.
2) Chrome obeys the current DE but we haven't figured out how to change
the settings in KDE.

The fact that Chrome pays attention to a $DE environment variable
(rather than just assuming it's on Gnome) makes me think the problem is
2 and not 1.

In fact I suspect that Chrome just uses xdg-open. I think the solution
to all this may be centered on xdg-settings, the manual for which gives
this example:

xdg-settings set default-url-scheme-handler mailto evolution.desktop

However I still haven't figured out the proper incantation for magnet (I
may have to set up a qbittorrent.desktop file, which currently doesn't
exist).

This is all theory of course.
