That's not a bug; that's parody of a horrible user interface.

'system-system-spacing is usually a list of pairs defining
'basic-distance, 'minimum-distance, 'padding, and 'stretchability.

Using a list with one element, he defines stretchability only, 
making 'basic-distance and 'padding undefined.  The undefined 
parameters are taken as zero, which would be reasonable if not for
the mysterious way these parameters lost their default values.

On the slim chance that this was an honest misunderstanding, the way to set
'stretchability, while leaving the others at their non-zero default values, is
  system-system-spacing #'stretchability = 666
