Sorry to answer so late.
This message occurs when you try to cut a multimeasureRest using
\extractMusic, in the middle of the measure.
For example
music = R1*5
\extractMusic \music s1 s4
will produce an error because the result is R4, and R4 doesn't fill a whole
measure (in 4/4) . It is not a limitation or a bug of \extractMusic but the
behaviour of Lilypond with multimeasureRests
So you have to cut them always at a beginning of a measure then add rests
manually.

The error is probably here, but you don't give us the \global definition, and
as \upToMeasure uses \global in his implementation, i cannot help you further.
