Comment 3 for bug 1878400

In the desktop file `org.kde.kdeconnect_open.desktop`, the `MimeType` is
`*/*`.

`update-desktop-database` is a tool provided in `desktop-file-utils` that

> updates the database containing a cache of MIME types handled by desktop files

When running `update-desktop-database`, it throws an error saying that

> "*/*" is an invalid MIME type ("*" is an unregistered media type)

This is reported in [Clear Linux](https://github.com/clearlinux/distribution/issues/1906) and [Arch Linux](https://bugs.archlinux.org/task/65865)

STEPS TO REPRODUCE
1. Run `update-desktop-database`

OBSERVED RESULT
> "*/*" is an invalid MIME type ("*" is an unregistered media type)
