 Folks,
   running the leastsq example from
 http://docs.scipy.org/doc/scipy/reference/tutorial/optimize.html
 with different random seeds
 -> ~ 20 % of the fits are way off, A ~ 0;
 don't know if this is a bug, or just local minima ?
 (hope my attached files get through, new here)

 Thanks, cheers
