backtrace on bridgedb

i'm seeing this in my console once in a while after starting bridgedb by hand.

Traceback (most recent call last):

i don't know if this is a known problem, and i don't have time to look back in the filed issues (sorry!)

i had to redeploy bridgedb after the bullseye upgrade (tpo/tpa/team#40692 (closed)) to keep it from crashing on start. i think it was crashing because there was python 3.7 specific stuff in the venv, while bullseye has 3.9.

i followed https://gitlab.torproject.org/tpo/anti-censorship/team/-/wikis/Survival-Guides/BridgeDB-Survival-Guide#deploying-a-new-version-of-bridgedb

and basically did:

~/bridgedb-admin/bin/deploy-production

... so now it runs seemingly correctly, but it gives that backtrace once in a while.
