Please, read section 6.1 of the committer's guide.

The XML of the key file should now be OK, or did you mean the non-expiring key?

Subversion seems to think that the file is a binary, and it has a non standard svn:mime-type. Please, svn rm it, and add it again, the only property it should have is svn:keywords with FreeBSD=%H.

Something more like:

$ svn pl -v mat.key
Properties on 'mat.key':
  svn:keywords
    FreeBSD=%H

I added $FreeBSD$ to the key file and had to use svn propset still. Maybe SVN is outsmarting itself here with the mime-type?

Please, use the addkey.sh script to generate the file, it will do that the right way, and it would have told you what commands to run to add the file.
