Bug Description

Every time update-desktop-database runs (e.g. in a package's postinst script), it complains about a broken MIME entry in /usr/share/applications/org.kde.kdeconnect_open.desktop:

  Error in file "/usr/share/applications/org.kde.kdeconnect_open.desktop": "*/*" is an invalid MIME type ("*" is an unregistered media type)

Steps to reproduce:
- sudo apt install kdeconnect
- sudo update-desktop-database

Expected behavior:
- No error message.

Actual behavior:
- Aforementioned error message, printed by update-desktop-database.

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

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

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)

Is that probably what the "all/allfiles" type is for?

I can reproduce this in v1.4, might be present in later versions too.

*/* is not a valid mime type. If I assume this mime type is supposed to include all files, the valid mime type for that is application/octet-stream.

Modifying /usr/share/applications/org.kde.kdeconnect_open.desktop to reflect the same fixes the issue.

You can fix this by changing */* to application/octet-stream as suggested by Saikat Patra.

There are patches to this end for a number of distributions all over the internet, like here: https://github.com/void-linux/void-packages/commit/17060bfa012b12896d3d7ec502caa154af6135b4, but it's an upstream issue.
