I checked a bit more.
ma.fix_invalid calls np.isfinite on the data part (a structured  
ndarray). Because the input is a structured array, np.isfinite returns  
a NotImplemented (a specific object of type NotImplementedType).  
np.logical_not chokes on that and raises the AttributeError exception.
I'm a bit surprised, I would have expected np.isfinite to raise a  
NotImplemented exception instead of returning something. I'll ask on  
the numpy mailing list.
cheers
