subDivideBeams issue

[Damian leGassick]

Hi

can someone explain why in the following the triplet beams are subdivided in 
bar 2, but not in bar 1 (I want them both subdivided as in bar 2)?

\version "2.15.26"
\relative c'' {
  \time 3/4
  \set subdivideBeams = ##t 
  \set baseMoment = #(ly:make-moment 1 8)
  c16[ c c c] c[ c c c] \times 2/3 {c16 c c c c c}
  c16[ c c c] \times 2/3 {c16 c c c c c} c16[ c c c]
}

thanks

Damian
