I don't think it's a bug. Looking at the code you quoted it seems the
anacrusis is 5 quavers, when it should be 8 (the same length as a
semibreve).

If you change `\partial 8*5` to `\partial 1` that should fix it.

(Barlines are usually placed automatically by LilyPond, and by setting
the anacrusis to 5 quavers LilyPond is putting the first barline in the
middle of the dotted minim - which is why you see the odd spacing where
the first crotchet afterwards is too far to the right.)
