ZF-2677: magic data model class creation methods throwing error if class isn't in first registered 'classpath'
Changes committed in r7577 removed error suppression (@) from the include_once call in Zend_Loader:83. This was eliminated in order to make sure that parsing errors, etc are discoverable. The magic method __call handing of 'new*' for data model class creation depended on these errors being suppressed. Need to suppress these errors in Zend_Gdata_App and Zend_Gdata_Gapps.
