Properties can't be added to structured properties

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Upload an app with a local structured property X, with property Y, and 
version 1.
2. Upload version 2 of an app adding property Z to X.  Do a request to version 
2.
3. Version 1 now fails reading the record put by version 2 with
RuntimeError('Unable to find property %s of StructuredProperty %s.'
                         % (next, self._name))

What is the expected output? What do you see instead?
  The unknown property should be ignored.

What version of the product are you using? On what operating system?
__version__ = '1.0.6' included with the appengine 1.7.3

Please provide any additional information below.

Can you show some more concrete code that I could run to reproduce your 
problem?
