[SciPy-user] Least Squares error message.

Hi all,
I'm trying scipy.optimize.leastsq routine and I get the following 
warning message as output:

> In [100]: lstSquareEstimate
> Out[100]:
> (0.029000567127575108,
>  'Both actual and predicted relative reductions in the sum of 
> squares\n  are at most 0.000000')

The message doesn't seem too much explicative (at least to me), and 
even after looking at scipy and MINPACK source codes, I've not got any 
further insight. Could someone try to explain what was going wrong 
here?

Thanks in advance,
  Andrea.
