Combine module makes Tuplets fail

[bwl21]

X:1
%%pagewidth 12cm
M:C
L:1/4
K:C
%%score 1 2
V:1
P:voicecombine -1
%%voicecombine -1
c (3ccc

produces the error noname.abc:10:8 Error: No end of tuplet

When I remove %%voicecombine the error persists until I reload the page. It appears to me that as long as the voicecombine module is loaded, Tuplets no longer work.

It happened in my app where I load the modules statically.
