More simply,

$ python3 -c 'from sphinxbase import sphinxbase'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/sphinxbase/sphinxbase.py", line 24, in <module>
    from . import _sphinxbase
ImportError: /usr/lib/python3/dist-packages/sphinxbase/_sphinxbase.cpython-311-x86_64-linux-gnu.so: undefined symbol: SWIG_Python_str_AsChar

and indeed, in swig's ./CHANGES.current I can see 

2023-12-20: wsfulton
            #2190 Replace SWIG_Python_str_AsChar with SWIG_PyUnicode_AsUTF8AndSize.

So this needs fixing (just rebuilding sphinxbase doesn't work). I can
see in
https://codesearch.debian.net/search?q=SWIG_Python_str_AsChar&literal=1
that a lot of packages might be affected by this incompatibility...
