This is a bug, unfortunately not fixed on sf yet :/  I'll have a look at it
tonite. In the meantime you can build the same qualifier by hand:

  >>> from Modeling.Qualifier import *
  >>> q=3DKeyValueQualifier('foo', QualifierOperatorGreaterThan, 3)
  >>> print q
  (foo>3)
  >>> ec.fetch('foo', q)

You can have a look at test_Qualifier.py for other examples.

        HTH,
