programming error: stopped tuplet bracket has left nor right bound

[James Wilkinson]

I found a trick, I believe in the snippets, that enabled me to extend a 
crescendo across a rest. That involved adding a parallel voice made up 
of spaces and attaching the crescendo to them instead of to the notes. 
It worked, and I got correct output, but it gave the message quoted 
above. I've included a bit of the music and all of the log file below. 
Measure numbers are included in comments at the ends of lines. It was 
the code for measure 2 that caused the error messages.

I found a couple of mentions of this message in the archives, but I 
didn't find a resolution. Can somebody tell me how to get it to run 
without the error messages?


Also, I wonder if the error message shouldn't say "neither left nor 
right bound".


thanks, guys

If there is one word to describe me, that word would have to be 
"profectionist".
Any form of incompitence is an athema to me.
Metathesis??? Don't ax me.
Just between you and I, the grammar used by Americans are getting worse.
I can only help but wonder what the cause of this might be.
It just ceases to amaze me how it could be the case, but mostly I could 
care less.

I won't get into specifics because that was between he and I
