This one puzzles me. I can load these albums just fine (one at a time or together):

https://musicbrainz.org/release/53cb2b4d-1b03-4cb5-b77a-35639e6822a8
https://musicbrainz.org/release/45eec198-74a8-4fa6-8fb7-3e2992f8986b

However, if I try to load either of these albums, Picard crashes:
https://musicbrainz.org/release/b64eee45-abb1-3edd-8bb9-12e057f2da5b
https://musicbrainz.org/release/a0cc5446-5489-3d0e-9357-da3c409c0cff

This is consistently reproducible. I've tested whether it matters if you load another album first, and it doesn't. I've tested them both with the "other versions" menu, as well as loading them directly on a fresh instance of Picard and that doesn't matter either.

The debug log from my last attempt is attached.

Might be the same as https://tickets.metabrainz.org/browse/PICARD-1342? That didn't specify what action caused the problem.
