WMS GetFeatureInfo Filter: No results

My WMS GetFeatureInfo Filter (QGis Server 2.0.1) returns no results while there should be.
(The Identify GetFeatureInfo and the GetMap Filter works fine.)

Where does the query come from? It is not a valid GetFeatureInfo query because it is missing BBOX, X and Y parameters.

The query is generated by pressing the 'Search'-button in the QGIS Web Client.

It used to work in the 1.8 version.

And the query seems correct according to https://github.com/qgis/qgis-web-client :

Request URL:

When performing a search query using the above configuration,
the following get request will be made.

``http://localhost/wms/helloworld?SERVICE=WMS&VERSION=1.1.1&
REQUEST=GetFeatureInfo&LAYERS=Country&QUERY_LAYERS=Country&
FEATURE_COUNT=10&INFO_FORMAT=text/xml&SRS=EPSG:4326&
FILTER=Country:"name"+=+'africa'``

So maybe something changed in qgis server and qgis web client wasn't updated accordingly?

I don't think it's a QGis Web Client problem. Browsing the wms-url without using the web client doesn't return results either.

Maybe it's similar with #16279

I can confirm Carl's experience:

Using Debian package qgis-mapserver 2.2.0-1, I get a response for a getfeatureinfo request on a wms layer when using specific coordinates (x,y), but I get no result when I launch a getfeatureinfo request with the filter parameter.
