Thanks Andrey!

My package (jupyter-client) isn't listed there, as the (binary)
dependency is on python3:any.  But the build turns out to succeed when
python3 -> python3.12 but fail when python3 -> python3.13 - it's
sphinx-build that fails.

I still haven't solved the bug, but at least I know which change has
caused the breakage.

Best wishes,

   Julian
