qgis wfs server cannot serve geometryless tables

http://hub.qgis.org/issues/7534

In a project where there are geometryless tables everything seems to allow publish them with qgis wfs server. In the project/layer properties all the proper panels (ex. OWS server) seems to allow this operation, but then when accessing the wfs service with the WFS client, the table is not added correctly in the project. In the TOC shows a strange icon (instead the expected table icon) and the table of attributes is empty.

In the client the support for geometryless wfs tables should be available since

so it is a server issue.
