Hi,

WFS server should send data in GML2 format with that request. It is not
forbidden to send KML but then client should send an additional 
&OUTPUTFORMAT= parameter because standard mandates that GML2 is the 
default for WFS 1.0.

QGis should handle output from WFS 1.0 well. It is impossible to say 
what isgoing wrong by this information but here are some suggestions 
about how to gather more information.
- Send your request with a browser and save the result into a file 
through Show page source code option. Then you can try to open the file directly
with QGis or study it with GDAL utility "ogrinfo". Instead 
of browser you can use wget or curl.
- Install for example Fiddler2 proxy between QGis and WFS server 
so you can see what really happens in the discussion.

GDAL 1.9 supports WFS directly as source format and you can use 
ogr2ogr for converting data from WFS into other vector formats.
