Package: sphinx-common
Version: 9.1.0-6
Severity: important

A new build of xsimd fails with the error:

dh_sphinxdoc: error: debian/libxsimd-doc/usr/share/doc/libxsimd-dev/html/_sources/build.rst.txt is missing


xsimd has no special configuration for dh_sphinxdoc,
and definitely no explicit reference to build.rst.txt 

Is this error a new feature of sphinx 9.1.0-6?
Are other packages affected?
