I get the same results when I was compiling a piece for our churchchoir.

The output is defective, because a slur is not completed over a break, just as 
a descrecendo in the following snippet from that piece:

I am trying to file a bug-report about this, but I do not know if this is 
succeeded.

BTW.: Does anybody know how I can get an indication on which part is sung 
where, usually it is Soprane, Alto, Tenor, and Bass, but in the scores I get 
they are sometimes changed, because they are taken from copies of old books.
