serializeToString exception with xmldom@0.1.20

[app17]

The tiapp.xml component is broken with the lastest version of xmldom (also reported in other components that are dependent upon this module e.g. jindw/xmldom#146)

Raised when trying to use the setModule command

tiapp.setModule('ti.cloudpush', {
            'platform' : 'android',
            version: '3.3.8'
        });


        "Warning: Object ti.cloud has no method 'serializeToString'� Use --force to continue."

It works with xmldom@0.1.19 but not on xmldom@0.1.20

Quickest fix is to lock xmldom to 0.1.19 in package.json
