automaticMelismata broken on 1.3.144

[Mark Hindley]

I have a complex ly file. If I set

\paper{
    \translator {
        \StaffContext
        automaticMelismata = ##f
        }
}      

lily compiles it fine, although the lyrics are in the wrong place

If I set automaticMelismata = ##t then ly2dvi croaks with:

paper output to vict-imp.tex...
programming error: Improbable offset for translation: setting to zero 
(Continuing; cross thumbs)

I can't see that there should be any error in the source file if it
will compile with automaticMelismata = ##f. Is there a problem with
automaticMelismata?
