Attaching reproducer.

From Fedora bug:

When I attempt to build a score using a PianoStaff or GrandStaff (which contains more than one sub-staff), lilypond crashes.

Reproducible: Always

Steps to Reproduce:
1. Attempt to build a minimal reproducer (which I will attach) with lilypond-2.25.4
Actual Results:  
Slightly varying modes of crashing.

#1) Without dumping core:

--- 8< ---
nils@makake:~/music> lilypond minimal.ly 

GNU LilyPond 2.25.4 (running Guile 2.2)
Processing `minimal.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
/usr/share/lilypond/2.25.4/ly/init.ly:64:2: error: Guile signaled an error for the expression beginning here
#
 (let ((book-handler (if (defined? 'default-toplevel-book-handler)
In procedure scm_hash_fn_create_handle_x: Error while printing exception.
--- >8 ---

#2) With dumping core:

--- 8< ---
nils@makake:~/music> lilypond minimal.ly 

GNU LilyPond 2.25.4 (running Guile 2.2)
Processing `minimal.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
/usr/share/lilypond/2.25.4/ly/init.ly:64:2: error: Guile signaled an error for the expression beginning here
#
 (let ((book-handler (if (defined? 'default-toplevel-book-handler)
In procedure scm_hash_fn_create_handle_x: Wrong type argument in position 1 (expecting hash-table): Segmentation fault (core dumped)
--- >8 ---

Expected Results:  
It builds a PDF from the score.

- I get the same behavior on Fedora 38 and Rawhide.
- Using the lilypond-2.25.3 Fedora package _or_ the 2.25.4 binary from upstream doesn’t exhibit the issue.
