Tuplet Bus error

[Joey Coyle]

Hi,

Why is this tuplet in \partition bad?  I copied it from the docs...    
Slowly but surely, I may figure this out....................

thanks,
joey


\header{
  title = "A scale in LilyPond"
}


\version "2.10.10"



\layout{
 \context{
   \TabStaff
   \override TimeSignature #'stencil = ##f
 }
 \context{
   \TabVoice
   \remove Beam_engraver
   \remove Stem_engraver
   \override TupletBracket #'number-visibility = ##f
 }
}



partition = {
    \key e \major

    \times 2/3 { f8 g a }
}


<<
\new Staff {
        \clef "G_8"
    \partition }
\new TabStaff {
    \partition
}
