Seems France is not amused with the United States disclosing oribital parameters for French comm and recon satellites. They have, at least implicitly, threatened to retaliate: http://www.space.com/news/060707_graves_web.html
There's no 100% proof that the 'phantom' satellites in question are in fact American, but I believe that to be a reasonable inference. American reaction has been to deny the existence of the satellites, even though the Graves radar system can detect solar panels on them.
I suppose if the US can publish a catalogue of orbital debris and other nations satellites, and exmpt its' own military ones, it's only fair if France can do the same.
