how to resolve note collisons ?

Gilles Harfang a écrit : 

Modify the "basse" \context, as follows:

%-----
  \context Staff = "basse" <<
    \global
    \clef bass
    \context Voice = "basse" { \voiceTwo \basse }
    \context Voice = "choral" { \voiceOne \choraltheme }
  >>
%-----

With the above, it won't be necessary to try and move that note.

Ma réponse :

Thank you for your answer.

But this did not help me. The problem remains (with 2.4.2 version) 
exactly the same.  I have the very same warning message during 
compilation (translated from french) :

Warning : too much "column-note" collisions. Will be ignored.
