Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> make[2]: Entering directory '/<<PKGBUILDDIR>>/docs'
> sphinx-build -b html -d _build/doctrees   . _build/html
> Running Sphinx v4.3.2
> 
> Exception occurred:
>   File "/usr/lib/python3/dist-packages/nbconvert/filters/markdown_mistune.py", line 31, in <module>
>     class MathBlockGrammar(mistune.BlockGrammar):
> AttributeError: module 'mistune' has no attribute 'BlockGrammar'
> The full traceback has been saved in /tmp/sphinx-err-xx45dgnc.log, if you want to report the issue to the developers.
> Please also report this if it was a user error, so that a better error message can be provided next time.
> A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!
> make[2]: *** [Makefile:53: html] Error 2
