Bug:130640 reports that as of KOffice 1.5, we aren't providing metadata support, and further identifies that the reason is related to the mimetype entries in the kfile_ooo.desktop file.

I've updated it to include all the vnd.oasis.opendocument.*
entries that are provided with current kdelibs, and also changed the name of the file type (from OpenOffice.org to Oasis OpenDocument).

This might be a candidate for backporting to the 1.6 branch if anyone has a checkout handy.
