shapeII (openlilylib) with v2.19.25

[Simon Albrecht]

Hello,

I have a problem with \shapeII (from openlilylib; in the override-like form) using v2.19.25. The following snippet:
%%%%%%%%%%%%%%%%
\version "2.19.25"
\include "notation-snippets/shaping-bezier-curves/shapeII.ily"

{
  \shapeII #'((0 . 2)) #'(Slur)
  c''( b)
}
%%%%%%%%%%%%%%%%

has been working up to v2.19.23, but with .25 I get

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3: error: wrong type for argument 3. Expecting music, found (list (quote Slur))

\shapeII #'((0 . 2)) #'(Slur)

/tmp/frescobaldi-5ZX7nT/tmpQSaLj0/test-shapeII.ly:5:3: error: error in #{ ... #}

\shapeII #'((0 . 2)) #'(Slur)

and the override has no effect.
The problem does not lie with the symbol-list-or-music? predicate in itself, as I might have suspected (but of course such a defect would have shown up much earlier), and I don’t know where to search for the problem.

TIA for any help,
Simon
