Are you using an old 5.6 beta? This issue was fixed in 5.6-beta4:

Yes, to use wms_feature_info_mime_type you need real TEMPALTEs in your 
queryable layers. This metadata is there exactly to specify what format 
the query templates return.

Note that in 5.6, with the new templating mechanism introduced in 
RFC-36, you can generate output formats such as GeoJSON, etc which may 
better suit your needs than GML or straight text/html. See
