Bug#1000815: skimage FTBFS: sphinx_gallery.docs_resolv error

[Rebecca N. Palmer]

Package: python-skimage-doc
Version: 0.18.3-2
Severity: serious

skimage fails during the documentation build with

embedding documentation hyperlinks for auto_examples... [  1%] 
plot_censure.html

Extension error (sphinx_gallery.docs_resolv):
Handler <function embed_code_links at 0x7f5b2229b5e0> for event 
'build-finished' threw an exception (exception: list indices must be 
integers or slices, not str)

I don't know what caused this, beyond that it worked on 2021-11-14:
