Yes Im seeing this too. It builds correctly with Sphinx 1.3.3

The problem is somewhere in the patches api autodoc. Disabling this and it builds correctly.

Note to self. The issue is somewhere in the ConnectionStyle docs. The error from sphinx is not very help full

@tacaswell tacaswell added this to the next major release (2.0) milestone Jan 17, 2016

Do we think sphinx broke or was fixed between 1.3.3 and 1.3.4?

I don't know yet. We will see when I have found the exact spot. I am in the middle of manually bisecting it. I definitly think the error message could be better and will probably report that at the least.

It seems to fail on matching the parenthesis in *angle* : angle of the connecting line (if None, parallel to A and B) on https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/patches.py#L3021 due to the new line. Removing the newline fixes the compilation (but violates pep8 )

Should probably just re-do that docstring as proper numpydoc style...

Related : sphinx-doc/sphinx#2247 ?

That looks quite likely

For reference sphinx-doc/sphinx#2247 has been resolved by Sphinx 1.3.5 and our docs build with a single warning. Solved by #5872
