"Too many clashing notecolumns" message

[ymorin]

        Hello !

        I'm new on the list. I installed LilyPond 1.4.12.jcn5 for Windows 
(Win98 SE) with Cygwin at the beginning of June. Install was OK.

        I've got the following message from my LilyPond console (marked by a 
'<==='):

Calculating column positions... warning: Too many clashing notecolumns.  Ignorin
g them.

        What does it means ? How to avoid it ? Does a detailled list of error 
messages exist somewhere ?

Here's the output of my LilyPond console:
