I did get xdg-open itself to work. Although all the different files and tools
confused me a lot.
I added the lines to mimeapps.list directly, although I think xdg-mime default
alone worked for me too.
I added a [Added Associations] line with the same entries as [Default
Applications].
Not really sure what this does though.
The mimeapps.list file I use is in /etc/xdg/ (global), so I set it from the
template.
Sometimes I've had to add a MimeType field (something like
MimeType=video/mp4;video/x-matroska;video/webm) to the .desktop file being
used, before running xdg-mime, to get it to work.

I added export XDG_CURRENT_DESKTOP=XFCE to my template, shut it down and ran
qvm-open-in-dvm to open a file in it.

It started and shut down. I get the same error in journalctl on qvm-open-in-dvm.

I downloaded Fedora 39 minimal, it didn't have mplayer, so I tried updating and
installing only kmplayer.
It seems to install a lot of plasma, Qt stuff, about 200MB in total.
After installing kmplayer it qvm-open-in-dvm didn't work.
With journalctl in the fedora based vm it shows the same failed to connect to
bus error as debian started with.
After that it seems to just give an mime error, like the one you showed earlier.
cat /usr/share/applications/mimeapps.list shows org.gnome.Totem as the default
application.
XDG_CURRENT_DESKTOP was set to X-QUBES, as with you.
I copied mimeapps.list to /etc/xdg/ in the template and replaced
