I have uploaded Sphinx with this change today, it now raises a warning
instead of AssertionError on types mismatch.

So downgrading the bug severity.

I agree that there is a breaking change in Sphinx 1.6.4: instead of printing
a warning about type mismatch, it raises AssertionError.

However in my opinion the real issue here is in breathe, and it should be
fixed in the first place. I have just created an upstream pull request about
this, and with that change applied breathe builds fine.

I will also create a pull request to sphinx fixing the regression, but unless
there are other affected packages I will not backport it to Debian before new
upstream release.

I can reproduce the problem and that downgrading Sphinx
to 1.6.3-2 fixes it.
