The languages for 2.3.22 and 2.3.23 are identical, convert-ly only does 
changes when backward compatibility has been broken somehow.

Remove the following line, and it works fine:

The best thing is always to send a complete (but reduced) .ly file  score, 
which reproduces the problem. I.e., so that you can take exactly what you 
wrote, place it in a file called foo.ly, and run "lilypond foo.ly" to 
reproduce the problem.
