LilyPond export creates a syntax error for Coda signs at the end of a repeat among rests

I am getting lilypond export with lines like "R1 \gotocoda *4" , provoking "syntax error, unexpected '*'". That's because this is an error. I think the correct lilypond notation would be "R1 *4 \gotocoda".

I've attached a sample musescore file that contains the construct that exposes this bug. I believe the issue is related to add a "D.S. al Segno" or similar mark at the end of a series of whole rests, inside a repeat.
