[Grok-dev] ConfigurationError: ('Unknown directive', u'http://namespaces.zope.org/browser', u'form')

[Jose Galvez]

after importing zope.app.content and zope.app.file into my setup.py file 
I get the following error when I try to start the app

zope.configuration.xmlconfig.ZopeXMLConfigurationError: File 
"/home/jc/pytest/music/parts/etc/site.zcml", line 4.2-4.29
     ZopeXMLConfigurationError: File

     ZopeXMLConfigurationError: File

     ZopeXMLConfigurationError: File

line 9.2
     ConfigurationError: ('Unknown directive', 
u'http://namespaces.zope.org/browser', u'form')

I don't even know where to begin to trouble shoot this, so any help 
would be appreciated
Jose
