Error remains the same since kdelibs-4.1

I am using several gnome (rather gtk) applications along with KDE apps, it
might be the case that the problem arises due to this. However, I do have
-gnome in my use flags.

Reproducible: Always

It's not KDE-related bug, the same output on any emerge

I Have the same issue. After removing appropriate records from
/usr/share/mime/packages/kde.xml messages disappear.

Already filed upstream, https://bugs.freedesktop.org/show_bug.cgi?id=16816

A patch should be filed soon.

It does the same thing, running Gnome, it's not KDE-related. 

Guys, have you been using VLC one day or another? Seems to me this message
appeared after unmerging it.

Not, in my case they appeared yesterday after updating (amd64), but I didn't
have vlc installed :-|

So, there's a patch, yes?
Does this mean portage should use the -q option?

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

Yeah, this worked like a charm... I just commented them out with html comments
and it stopped giving me errors.
Thanks for the hint.
