Are you sure that the .ly snippets were actually rebuilt?  "make clean" 
does not delete them, IIRC.  Please also note that, during "make web", 
lilypond is called with the option:

-e '(ly:set-option (quote internal-type-checking) #t)'

Without explicitly adding this option (e.g. when calling lilypond 
manually), lilypond will not issue any "Grob 'xyz' has no interface for 
property ..." warning.
