bug with tupletFullLength

[Thomas Morley]

The following code gives a log warning:

\version "2.15.30"
\new Staff {
   \set tupletFullLength = ##t
%   \override TupletBracket #'full-length-to-extent = ##f
   \time 1/8
   \times 2/3 { c'16 c' c' }
\mark "123456789"
}

log:
warning: Found infinity or nan in output. Substituting 0.0



If the mark contains less than 8 characters the warning disappears.
Same, when commenting in \override TupletBracket #'full-length-to-extent = ##f

Compiles without warning using 2.12.3
