Hi,

I'm now trying out "new" pattern miner.

"Simple" example seems to work (I guess, or not?):

$ guile -l simple.scm

scheme@(guile-user)> (cog-mine (cog-atomspace) #minsup 2)
$1 = (SetLink
   (LambdaLink
      (VariableList
         (VariableNode "$PM-4c2b3a57")
         (VariableNode "$PM-e84bdd8")
      )
      (InheritanceLink
         (VariableNode "$PM-4c2b3a57")
         (VariableNode "$PM-e84bdd8")
      )
   )
   (LambdaLink
      (VariableNode "$PM-e84bdd8")
      (InheritanceLink
         (ConceptNode "A")
         (VariableNode "$PM-e84bdd8")
      )
   )
   (LambdaLink
      (VariableList
         (VariableNode "$PM-51de97f")
         (VariableNode "$PM-a083600")
      )
      (VariableList
         (VariableNode "$PM-51de97f")
         (VariableNode "$PM-a083600")
      )
   )
   (LambdaLink
      (VariableNode "$top-arg")
      (VariableNode "$top-arg")
   )
)

However, "ugly-male-soda-drinker" example fails. It gives the following:

Backtrace:
           5 (apply-smob/1 #<catch-closure 
5654470958c0>)

      )
      (AndLink
         (InheritanceLink
            (VariableNode "$PM-793e6063")
            (VariableNode "$PM-762382f3")
         )
         (InheritanceLink
            (VariableNode "$PM-793e6063")
            (ConceptNode "ugly")
         )
         (InheritanceLink
            (ConceptNode "Cason")
            (VariableNode "$PM-762382f3")
         )
      )
   )
...
(data dump continues)

I'm not sure this is a bug or my build/configuration problem (or expected 
behavior).  Could you give me hints?

Best regards,
MH
