worked out of the box and spits out a few 100 lines of proof ending with

 r:gives {
  _:sk1 owl:differentFrom _:sk1.
  <http://penguin-house.example/2008/article2> owl:differentFrom <

 }].

#ENDS 160 msec


Eye does bnode to univar rewriting in the rule premis and that rewritten 
form is used in the proof..
Apart from that, check.py should now be happy with the proof, be it that 
it is a bit redundant
i.e. up to 518 steps

   * - 518
     - @forSome :_g0 . xx:Bob owl:differentFrom xx:Bob . <

http://penguin-house.example/2008/article2> . :_g0 owl:differentFrom :_g0 
.
     - conjoining steps (169, 338, 517)
     - 
 
versus 144 in your http://www.w3.org/2001/tag/dj9/badmeta-pf.html

I got it to work by commenting out the assertion;
cwm complains a little bit, but the proof checks.

This is fun stuff...
