Comment 10 for bug 289592

I'm not sure, but why

mention this bug as a "fix"? It looks like kde.xml does something unusual and either this should became allowed in specification or prohibited. But in any case trying to hide the problem does not sound like a good solution. So I guess the real question here is, what do do with the following mime:

  <!-- all/ fake mime types -->
  <mime-type type="all/all">
    <comment>all files and folders</comment>
  </mime-type>

Should update-mime-database warn about them or ignore?
