qubes-open fails

Since a day or two, I get the following error messages when attempting
to open a file in a DVM...

"Unable to handle mimetype of the requested file (exit status: 768)!"

So I started the VM that is the template for the DVM

qvm-run -a dvm-offline xterm &

and experimented...

1) calling xdg-open directly works
2) calling qubes-open does not

user@dvm-offline:~$ xdg-open test.pdf
user@dvm-offline:~$ qubes-open test.pdf
xdg-mime: mimetype argument missing
Try 'xdg-mime --help' for more information.

What could cause this? I haven't actually changed anything other than
running regular updates on the template. As far as I can see
qubes-open is a wrapper script around xdg-open setting some
environment variables.

I restored the template from backup and the issue is gone. My best bet
is that it was me running dnf autoremove and saying "yes" to something
that I shouldn't have.
