It doesn't, it simply hides the issue.

Also, sometimes exporting http{s,}_proxy simply breaks unit testing (I
did have such case, yes...). So that's not really a fit-all solution either.

I find this not the top-noch way. Here's what I do:

override_dh_sphinxdoc:
ifeq (,$(findstring nodocs, $(DEB_BUILD_OPTIONS)))
	PYTHONPATH=. sphinx-build -b html doc/source \
		debian/python-foo-doc/usr/share/doc/python-foo-doc/html
	dh_sphinxdoc
endif

IMO, that's better because you don't need to clean Doc/.build/html.
Also, the dh_auto_build isn't the correct target. Some derivative may
well choose not to implement dh_sphinxdoc (for example, for small
systems where they don't want docs), and here, you're making their lives
miserable.

Cheers,
