Turns out I was maligning core parts unjustly Image may be NSFW.
Clik here to view.
, in fact I had loaded this part (from elsewhere on the net) and mistakenly though it was in core.

At least one (and I suspect all) of the grove parts in core have been corrected. If you load this part in to fritzing it will look just fine in all views. However when you export the gerbers you will find that the drill file contains no holes (because the path does't create them):
; NON-PLATED HOLES START AT T1
; THROUGH (PLATED) HOLES START AT T100
M48
INCH
%
T00
M30
As well the pad images in the gerber are pixalated somewhat. So long as you stay in Fritzing, things will look fine (which is why breadboard appears OK), but when you want to produce boards, trouble comes because of the path command in the pcb svg.If you load the above part in to Fritzing you will see what I mean, within Fritzing all looks fine but export gerber doesn;t actually work.
