Unknown media types

[Michael Palimaka]

Hi,

kcoreaddons installs /usr/share/mime/packages/kde5.xml which causes the
following warnings when update-mime-database is executed:

Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'
Unknown media type in type 'uri/mms'
Unknown media type in type 'uri/mmst'
Unknown media type in type 'uri/mmsu'
Unknown media type in type 'uri/pnm'
Unknown media type in type 'uri/rtspt'
Unknown media type in type 'uri/rtspu'

This has been around for a long time, but are they actually used by
anything anymore and if not, is this a good opportunity to clean it up?

Best regards,
Michael
