Produces correct pdf output but also the following string of error messages
(the full piece of music showed similar inconvenient lack of line numbers
with the errors).

This
\version "2.14.2"
\paper{ ragged-right=##t }
\relative c'' {
\repeat percent 2 {\set tupletSpannerDuration = #(ly:make-moment 1 4)
\times 2/3 {
g8 f g  f g f   g f g  f g f
} \unset tupletSpannerDuration }
}

produces identical music but no error complaints, however in long passages  
of
triplets it's a nuisance to have to stop and start the tupletSpannerDuration
for chunks involving % repeats.
