Bad tuplet beam

[Jay Anderson]

I managed to simplify my test file to get a segfault with the following:

=====
\version "2.11.16"

\paper
{
 ragged-right = ##t
}

%57 - no segfault
%58 - segfault
spacer = { \repeat unfold 58 R2 }

\score
{
 \new PianoStaff
 <<
   \new Staff = "RH"
   {
     \time 2/4
     \clef treble
     \spacer
     r4 s |
     \spacer
   }
   \new Staff = "LH"
   \relative c'
   {
     \time 2/4
     \clef bass
     \spacer
     <<
       {
         \times 2/3 {bes8 bes bes}
         \change Staff=RH
         \times 2/3 {bes bes bes} |
       }
       \\
       {
         s4 \change Staff=LH r4 |
       }
     >>
     \spacer
   }
 >>
}
=====

I usually got this:

GNU LilyPond 2.11.16
Processing `test.ly'
Parsing...
Interpreting music...
[8][16][24][32][40][48][56][64][72][80][88][96][104][112][117]
Preprocessing graphical objects...Segmentation fault

But without changing the code I also got:

GNU LilyPond 2.11.16
Processing `test.ly'
Parsing...
Interpreting music...
[8][16][24][32][40][48][56][64][72][80][88][96][104][112][117]
Preprocessing graphical objects...ERROR: In procedure
ly:tuplet-bracket::calc-positions:
ERROR: Wrong type (expecting real number): ()

Really odd. I'm not sure what the difference was between the runs.

If you null out the 'spacer' variable you can see the beam for the
first set of triplets is misplaced (attached). Thanks!
