a quick test, after building lilypond including this patch still shows 
41,9pt. So there still seems to be an inaccuracy - maybe its a float 
very near 42 that is rounded/truncated/whatever to a tenth pt number 
while importing the PDF.
So as long there is no problem for the printer and the result on paper 
has the right size, I'd call this 'ugly' but not a top-list-issue.
