Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  *Void 5.6.7_1 x86_64 GenuineIntel uptodate rrrmFFFFFFFFFFFFFF*
* package:  
  *kdeconnect-20.04.0_1*

### Expected behavior
no errors messages
### Actual behavior
Every update of the MIME database generates a complaint:

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

### Steps to reproduce the behavior
install `kdeconnect`, update system.
