New issue 1764 by brownian.box: \displayLilyMusic causes error with  
\addFingering from LSR 768

Reported by Eluze,
http://lists.gnu.org/archive/html/bug-lilypond/2011-07/msg00429.html :

%--------------------8<--------------------------
\version "2.15.5"
% this code uses \addFingering from
% http://lsr.dsi.unimi.it/LSR/Item?id=768 :
\displayLilyMusic { \addFingering a #"-5" }

reports in the log:

GNU LilyPond 2.15.5
Processing `test.ly'
Parsing...ERROR: No applicable method for #<<extended-generic> map (0)> in  
call (map #<procedure #f (tweak)> #f)

without \displayLilyMusic it works.

I decided it's "Type-Other".

Can it be related to Issue 1733?
