Further problems. I commented out the Time settings and here's more, this time in the RH (note paired semiquavers in LH here, which would be in sixes).

This is now built with revision 35 (the latest).

Hi, 

I'm wondering whether anyone can shed some light on the attached image.

LH of the piano here is:

{
 bf,16 (ef g8) r8
  c,16 g' c, g' bf, g'
  \clef bass
}

I have a suspicion this may have something to do with the Timing / beat moment and beat structure, but it's inconclusive. This section of the music has:

  \set Timing.baseMoment = #(ly:make-moment 1/16)
  \set Timing.beatStructure = #'( 6 6 )

There are no barline errors, but I'm seeing this in the output quite a lot: 

programming error: mis-predicted force, 108.120472 ~= 101.465263

continuing, cross fingers

programming error: mis-predicted force, 108.120472 ~= 105.654382

continuing, cross fingers

programming error: mis-predicted force, 108.120472 ~= 101.465263

Previously I was getting a similar issue where I had bars of 6 quavers, which were grouped in 3's -- and the middle of the second group was getting a spurious semiquaver beam. I seem to fixed it, though I'm not sure what the cause was.

Thanks in advance,

Chris

P.S. Using Lilypond 2.19.28.
