@colesbury figured out that it's caused by this code decrefing qidobj too many times.

@ericsnowcurrently, I'm preparing a PR for this but let me know if you were already working on it.

@swtaarrs I'll gladly review your PR. Thanks for taking care of it!

What's your ETA? Per #76785 (comment), @encukou may revert gh-115566 within the next few hours.
