Thanks for the heads-up on this. I haven't had a chance to look at the code yet, but I have a good guess as to what's happening and how to fix it.

When two ledger lines are at the same vertical position, in the same note column, (as I assume is probably the case with a pitched trill note?) we apparently can't just assume that they overlap horizontally (as is most often the case with chords). We will have to check whether they overlap horizontally or not before merging them.

If this is indeed what is going on, I don't think it should be very hard to fix. I'll try to take a crack at it when I get a chance, hopefully within a week. So at this point I'd prefer not reverting, but fixing it with a new patch.
