emacsclient.desktop advertises x-scheme-handler/org-protocol as a
supported MIME types, but uses the %F field code (i.e. a list of files)
in its Exec key.

According to the Desktop Entry Specification, a non-file MIME type like
x-scheme-handler/* must not be paired with %F but with %U.

KDE warns about this at runtime (e.g. when trying to open a file in its
Dolphin file manager):

kf.kio.core: "/usr/share/applications/emacsclient.desktop" contains supported protocols but doesn't use %u or %U in its Exec line! This is inconsistent.


Unfortunately, I don't see a good way to fix this. Replacing %F with %U
might work for some applications, but the spec says about the %U field
code: "Local files may either be passed as file: URLs or as file path.",
and passing file:// to emacsclient won't generally work.

I've also tried adding both %F and %U but it is not valid either:

$ desktop-file-validate emacsclient.desktop 
emacsclient.desktop: error: value "sh -c "if [ -n \\"\\$*\\" ]; then exec emacsclient --alternate-editor= --display=\\"\\$DISPLAY\\" \\"\\$@\\"; else exec emacsclient --alternate-editor= --create-frame; fi" sh %F %U" for key "Exec" in group "Desktop Entry" may contain at most one "%f", "%u", "%F" or "%U" field code

A possible solution would be to drop x-scheme-handler/org-protocol
from emacsclient.desktop, and split it off into its own desktop file:

---------- 8< ----------
[Desktop Entry]
Type=Application
Name=emacsclient (org-protocol)
NoDisplay=true
Comment=Tell a running Emacs to handle an org-protocol link
Icon=emacs
Exec=emacsclient %U
Terminal=false
MimeType=x-scheme-handler/org-protocol;
---------- >8 ----------

However, adding yet another desktop file looks like overkill.
(And considering Eli's reply in bug #79066 it won't be a viable option.)
