Description
WFS 1.0.0 Client requests made from QGIS 2.8.1 will fail against Geoserver (tested on 2.7.1) if the request contains a Filter that uses geometries.
From the WFS log console:
DescribeFeatureType failed for url http://localhost:8080/geoserver/ows?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=xxxx:yyyy&SRSNAME=EPSG:4326&FILTER=<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc">
<ogc:Intersects>
<ogc:PropertyName>geometry</ogc:PropertyName>
<gml:Point>
<gml:coordinates cs="," ts=" ">-91.5,34.5</gml:coordinates>
</gml:Point>
</ogc:Intersects>
</ogc:Filter>
Note that the Filter's opening XML tag includes the "ogc" namespace, but it never defines the "gml" namespace.
My naive attempt at debugging: I see that geometryFromGML is overloaded in https://github.com/qgis/QGIS/blob/master/src/core/qgsogcutils.cpp. Only one of them contains logic to set the "gml" namespace, and I suspect that the qgswfsprovider.cpp might be invoking the wrong one.

For context, in the above case, I had used the expression string builder to issue the filter:intersects($geometry, geomFromWKT('POINT(-91.5 34.5)'))
The geoserver-side error is:org.geoserver.platform.ServiceException: org.xml.sax.SAXException: Attempted to construct illegal filter - I dont understand the tag: gml:Point. HINT: tags are case-sensitive!

Hello, bug triage...
this is also true for an attribute filter (tested on QGIS 2.13 master):
DescribeFeatureType failed for url http://geoservices.brgm.fr/geologie?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=MINES_EMP&SRSNAME=EPSG:4326&FILTER=<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc">
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>substance</ogc:PropertyName>
<ogc:Literal>Pb</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:Filter>

This must be re-tested with qgis 2.18.*/master as the wfs client has been overhalued meanwhile.

Now using QGIS 2.18.4, I have tried both the "intersects" and the "attribute" test cases mentioned earlier in this issue, and they both work as expected.
This appears to be fixed. Thank you!
