Zero export

Hello,

I have loaded organisationunits directly into an empty database (and in the process removed the uniqueness constraints for name and shortname, which we should do also in trunk, as discussed before).

I did also populate the source table (did not remove the foreign key).

However, when I try to do a metadata export, all I get is an empty DXF file. You can try it yourself here: http://97.107.142.53:8080/repo/
