Thanks Duncan for pointing me to the problematic file.

I could live with VLC being default for audio and video. But VLC have hooked 
in on almost everything like rpm-specfiles, shell scripts, text files. Even all 
OpenOffice file types (OpenOffice files  still is default to OpenOffice because OO 
seems to have a higher priority).

So removing VLC associations via KDE settings seems to be a huge job.

Yes had looked on this file previously, but nothing in this file seems to 
explain why VLC is associated with unrelated files.

There is a lot af mime types, but to me they all seem legitimate for a media 
player.

I am unsure what they do:
klaus at roaster:~> grep X-KDE /usr/share/applications/vlc.desktop
X-KDE-Protocols=ftp,http,https,mms,rtmp,rtsp,sftp,smb

But anyway I never messed around with this file and other user accounts on this 
machine do not have VLC dominate everything.

And this directory was where the problem was! Here  I found 2 interresting 
files: mimeapps.list  vlc-2.desktop

Replacing both with files from another user stopped VLC world domination.

Thanks again.
