I did do a few quick tests already (on 13.2), and it indeed seems to work as
intended, including fixing xdg-open.

I.e. both: "inode/directory=kde4-ark.desktop;" and
"inode/directory=kde4-ark.desktop;kde4-dolphin.desktop;" in
~/.local/share/mimeapps.lists make "xdg-open ." start ark now with this change
(I don't have Krusader installed here so used something different, it of course
gives an error message that it cannot open /home/xxx/, but that's irrelevant
here... ;-) ), while they called Firefox before.
