 Well, I finally took some time to track this down.  It is indeed,
 unrelated.  Cutting down my idx file, the culprit is:

 {{{
 \indexentry {!=@\lstinline []{!=}|hyperpage}{288}
 }}}

 So xindy does not like ! in entries that do not start with something.  I
 can understand that, since it can be used as a separator of sub-index
 entries (see http://en.wikibooks.org/wiki/LaTeX/Indexing for instance).  I
 had never noticed I had a problem there, since makeindex did not complain,
 but did not issue the index entry, indeed.

 To summarize:
  * this is clearly a bug in xindy which forgets to check that the string
 before ! is not empty
  * this is clearly a bug in my document and I need to find a means for
 makeindex/xindy to accept this != entry.

 I meant to answer here, since Google makes it the best match for {{{ERROR:
 CHAR: index 0 should be less than the length of the string}}} :)
