Hi Paulo,

Will you run these again with the latest SVN version of numpy.   I 
couldn't figure out why a copy was being made on transpose (because it 
shouldn't have been).  Then, I dug deep into the PyArray_FromAny code 
and found bad logic in when a copy was needed that was causing an 
inappropriate copy.

I fixed that and now wonder how things will change.  Because presumably, 
the dotblas function should handle the situation now...
