I'm fairly sure this is the change to docstring indentation, *again*. skimage is doing some fairly sketchy regex-based magic to generate docstrings for properties from a big docstring for a function:

def _parse_docs():
    import re
    import textwrap

    doc = regionprops.__doc__ or ''
    matches = re.finditer(
        r'\*\*(\w+)\*\* \:.*?\n(.*?)(?=\n    [\*\S]+)', doc, flags=re.DOTALL
    )
    prop_doc = {m.group(1): textwrap.dedent(m.group(2)) for m in matches}

def _install_properties_docs():
    prop_doc = _parse_docs()

    for p in [member for member in dir(RegionProperties) if not member.startswith('_')]:
        getattr(RegionProperties, p).__doc__ = prop_doc[p]

...where the regionprops docstring text looks like:

    **area** : float
        Area of the region i.e. number of pixels of the region scaled by pixel-area.
    **area_bbox** : float
        Area of the bounding box i.e. number of pixels of bounding box scaled by pixel-area.
    **area_convex** : float
        Area of the convex hull image, which is the smallest convex
        polygon that encloses the region.
    **area_filled** : float
        Area of the region with all the holes filled in.

...so I'm pretty sure the deindentation thing is screwing it up (it's expecting four spaces before the text it wants to use as the property docstring). Testing a patch for it now, will clean it up and send it upstream if it works.

https://github.com/scikit-image/scikit-image/pull/7448 fixes the indentation thing. Orion reported the other two issues I saw in a mock build at https://github.com/scikit-image/scikit-image/issues/6993 , but he said there it magically went away for him after a bit. Not sure if it will for me. Trying a few things here.

aha, those bugs are due to a missing image file in the cached data tarball. will fix.
