OK, so this is working now after a bunch more bugfixes. I'm going to run it over the weekend, and then write a proposal for a proposed bugzilla replacement.
FYI, git-bug has a nice webui (this is running on localhost).
All of these bugs were tagged via the mailing list. See
https://lore.kernel.org/tools/It would be nice to write a bug viewer plugin for cgit, too, but this is for much, much later.
