weirdness in partcombine in current master

[address@hidden]

Hey all,

I tried to compile Keith's version of Dvorak's 9th and I got a lot of:

<string>:2:55: error: syntax error, unexpected MUSIC_IDENTIFIER, expecting 
TONICNAME_PITCH or NOTENAME_PITCH or PITCH_IDENTIFIER
      \transposedCueDuring \lilyvartmpbg #lilyvartmpbh 

This is both before and after running convert-ly.

Any ideas as to what may be the cause?

Cheers,
MS
