[Qgis-developer] Error import Processing

Hi
I am working with QGIS Valmiera 2.2.0 in a Windows 7.
I need import the library Processing, but I can't load. My code is as follow:

When I run this code, the program does nothing and doesn't gives errors. But i've been running slowly code and I have found that the statement fails is "import Processing".attached a image  when show an execution of the program:
              

thanks for the helpIván
