Problems with ties over line breaks

[Cameron Horsburgh]

Hi folks,

The score I'm working on has ties going over a page/line break. On the 
second page, one of the ties is hardly noticeable--in fact, I was 
alerted to the problem by what I thought was a misplaced staccato!

I haven't been able to reproduce the problem--any test cases I run turn 
out beautifully. So I'm afraid I'll have to submit the WDT. For size and 
copyright reasons I won't post it to the list--I've put it up at

The problem is at the beginning of page 3 on the second cornet line 
(compare with the first cornet and Eb Bass). I've moved the associated 
slur around as well to no effect.

This score was generated with the GNU/Linux GUB 2.7.39-2.

(Disclaimer: this score is still early in the debugging stage, so please 
go easy! Also, be aware that the piece I'm transcribing is copyright. 
The copyright owner won't mind me putting it up on my site for this 
purpose, but please don't do anything else with it!)
