Yes, you are hitting a known bug with the WFS stuff in OpenLayers.  This 
particular problem will be solved with the new WFS protocol (which will 
write out the xmlns attribute for the feature type namespace alias).

So, with apologies for the frustration, you'll have to wait a while 
before the WFS/GML facelift makes it in to the trunk.
