This is a problem in the getattr code of UserArray.   This is fixed in 
SVN.   But, you can just replace the getattr code in UserArray.py with 
the following:

    def __getattr__(self,attr):
        if (attr == 'array'):
            return object.__getattr__(self, attr)
        return self.array.__getattribute__(attr)


Thanks for finding and reporting this.
