commit 12e2fb525744084c83f943dd24665e2153dc6d0e
Author: Murray Cumming <murrayc murrayc com>

    Fix the tests after the libgdamm Null Value change.
    
    * tests/python/test_python_execute_script.cc:
      Do not try to instantiate a static Value instance because the constructor
      now needs the GType system to be initialized.
