[SOLVED] "Unknown media type in type [...]" for update-mime-database

When installing mysql-workbench, I get errors (warnings?) like this:

Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'

There are many more on my other installation (with KDE, instead of Gnome 3 - that's the only real difference I can think of):

Unknown media type in type 'chemical/x-vmd'
Unknown media type in type 'chemical/x-xyz'
Unknown media type in type 'all/all'
Unknown media type in type 'all/allfiles'

Should I be doing anything about it? Same errors appear when I'm trying to do:

# update-mime-database /usr/share/mime

These are harmless messages and you can ignore them.

This is not helping anyone nor does it describe the situation correctly. As I value arch bbs threads higher then others, i feel offended by this ^^

This is what I found out, I'm no expert, it just annoys me to death and I'm going the alter or delete the file after this post:

It's a bug. It won't be fixed, because of backward compatibility from KDE to KDE4.

Old KDE4 file contains bogus mime types:

/usr/share/mime/packages/kde.xml

New file, /usr/share/mime/packages/kde5.xml was fixed by devs here:

https://bugs.kde.org/show_bug.cgi?id=303627

git commit: https://github.com/KDE/kcoreaddons/comm … c10cab345e

Why I have the "old" file in a plain kde5 /plasma environment is beyond my knowledge:

pkgfile /usr/share/mime/packages/kde.xml
extra/kdelibs

It seems to be adependency to ~100 kde packages so uninstallable so far.

Some fixes are to remove the "fake" entries or rename the xml file :

http://askubuntu.com/questions/39852/ho … media-type

one possible way to rename the kde4 file, removes the "all/all" stuff:

$ mv /usr/share/mime/packages/kde.xml{,.bkp}

The "chemical" stuff might result from the kdeedu meta package. To get rid of only them you could consider removing "kdeedu-kalzium" and dependencies.

One needs to note the problem seems to be in the verbosity in update-mime-database, that should not complain after almost every system update, however.
As always in open source, small end user stuff will never be fixed. Here is a *8* year old request for that exact issue:

https://bugs.freedesktop.org/show_bug.cgi?id=16816

This is for the endless people that Google sends here.
