The new staff-spacing system has the concept of distinguishing staves from
lines that are attached to staves.  Both ChordNames and Lyrics are looking
for a staff in between them, so they can space themselves relative to it.
"staff-affinity" is the setting that controls which direction a line looks
for attachment. 

For your case, let one of the non-staff lines become independent, with
\new Lyrics \with { \override VerticalAxisGroup #'staff-affinity = ##f }

That warning message is bad.  Can anybody suggest better than :
"
Warning: two adjacent non-staff lines ask to be spaced relative to a non-
existent staff between them; need to change staff-affinity.
"
(I checked the code to confirm that this describes the situation LilyPond
is trying to handle, and she makes a guess and effectively changes one staff 
affinity.)
