lyricsto incompatible with auto-split durations

[Marco Gusy]

Hi all,
in my example if I rip off the

\with {  \remove "Note_heads_engraver"
   \consists "Completion_heads_engraver" }

lyrics is placed correctly, otherwise every note of the system (no matters
 the voice lyricsto refers to and ties/slurs are discarded) fire up a
 syllable.

I think it's a bug, i wish i didn't make any syntax mistake in my input
