    That's because we now delete all cached stuff when an exception occurs during build, so that a full rebuild has to be done.

    These KeyErrors are annoying, and I also get them from time to time when adding or removing files. I'd like to track them down, but at least people don't get stuck anymore and have to remove their doctrees by hand.

    I ran into this issue with the exact same stack trace and tracked it down. It happens when:

    • Using the html builder, having already completed a build
    • A document has been removed since the last build
    • The html .buildinfo config or tags hash has changed

    The pickled environment is loaded with found_docs containing the now-removed document. Then the html builder's get_outdated_docs, in the code path for changed config/tags, yields everything in found_docs without checking whether the document files still exist. This patch fixes it:
