I can reproduce by attempting to delete a card that has already been deleted. There could be protection implemented, but the limitation is already documented in CardsPlugin#KnownLimitations.

Right. I'd really like to do something about that limitation at some point. While double-deletes could usually easily be detected and ignored, I assume to solve the problem in general a combination of auto-refresh and conflict detection based on some kind of version number checks would be required. Suggestions welcome.
