\new Staff
<<
   {
     \voiceOne
     R1
     a''8( b'' b'' a'')
   }
   \new Voice {
     \voiceTwo
     r4 r r r
     r r r r
   }

exposes the problem as well.

I can confirm Lukas-Fabian's finding about first bad commit.

87eb2f9fe1be3a532675fe4b7322bbba5a60ba5c
patches `overdone_heads´ in feta-params.mf

So adding
\override NoteHead.font-size = 0.0001
to the examples fixes them in recent lily-versions

Interestingly 2.18.2 can be forced to return same bad output by
setting NoteHead.font-size accordingly:

\version "2.18.2"

\new Staff \with { \override NoteHead.font-size = 0.00005 }
 <<
   { R1 a''8( b'' b'' a'') } \\ { r4 }
 >>

\new Staff \with { \override NoteHead.font-size = -0.0001 }
 <<
   { \voiceOne R1 a''8( b'' b'' a'') }
   \new Voice { \voiceTwo r4 r r r r r r r }
 >>

Cheers,
