Still lyrics spacing problems

[Alois Steindl]

Hello,
I tried again to write a song for my wife and encountered problems with 
the spacing of lyrics.
Also after upgrading to 1.6.5 my problems persist:
The lyric texts are sometimes too close together (In the appended 
example the words "tanzt auf" in the last line.
Also the accompanying chords are strange: the 7 in g2:7 overlaps the G.
Is there a simple recipy to center align the lyrics syllables with the 
notes? (I couldn't get the lyrics-syllable-interface set correctly).
Quite certainly I am doing something wrong, but where should I look?
Best regards
Alois
PS.: I renamed the 1.6.4 lilypond hierarchy to make sure that no old 
style is used.
