> - non-default constructor coinsides with the default one...
  It seems problem here, I forgot about default ctor, but let's await 
the exact comment from Fons or Masa.
  Mean time try to use NON-default ctor. (We saw such sort of problem 
when some one wanted to create the array of histogram and failed)
