It's probably an error inside the Bar_number_engraver when it calls
scm_number_to_string () .  Since it's a Guile error, you don't get
line number info.

I couldn't really say what's wrong without seeing the full file, since
it works fine in minimal examples.

I wouldn't move the Timing_translator unless you really need to (i.e.,
for polymetric notation).  Why can't you set currentBarNumber at the
Score level while moving the Bar_number_engraver?
