property type-check from `instrument'

[Graham Percival]

input/test/  doesn't compile.

Renaming input to: `instrument-name-align.ly']

warning: can't find property type-check for `instrument' 
(translation-type?).  perhaps a typing error?
Abort trap (core dumped)

Should this be updated with convert-ly?  (I can't run convert-ly on this 
freebsd box), or is there a problem with the recent instrument name changes?
