 I was working on getting the info for #16048 and ran into a problem :)

 To test depictor without doing a ton of network i/o I uncomment lines [0],
 run ./write_website.py once to download and save the files, and then run
 ./website.py which will read the pickled files[1].

 [0] https://gitweb.torproject.org/depictor.git/tree/write_website.py#n61
 [1] https://gitweb.torproject.org/depictor.git/tree/website.py#n964

 This now fails. FWIW I downloaded the files and constructed the objects
 using validate = True in the downloader [2]
