[Python-modules-team] Bug#955058: speedcrunch: FTBFS with Sphinx 2.4: Could not import extension qtkeyword (exception: No module named 'sphinxcontrib')

[Felix Krull]

I do have a question: this is caused by the qthelp builder being
deprecated and moved to sphinxcontrib (but with a shim in the main
package). Are there existing plans to package
https://github.com/sphinx-doc/sphinxcontrib-qthelp or do I need to
take care of it myself?
