Each grace note in MIDI output has a length of 1/4 of its actual
duration. If the combined length of the grace notes is greater than the
length of the preceding note a “Going back in MIDI time” error will be
generated. Either make the grace notes shorter in duration, for example:

    \acciaccatura { c'8[ d' e' f' g'] }

becomes:

    \acciaccatura { c'16[ d' e' f' g'] }

Or explicitly change the musical duration:

    \acciaccatura { \scaleDurations 1/2 { c'8[ d' e' f' g'] } }

See Scaling durations.
