You can't have ties or slurs going between notes in different voices. I 
frequently encounter this problem when setting guitar music, which 
commonly has multiple voices on a single staff. I get around it by using 
an additional voice with hidden notes and duplicating the tied/slurred 
notes in this voice with the ties/slurs moved there. I would estimate 
that at least half of the several dozen guitar scores I have set with 
Lilypond have needed this workaround.
