A backtrace can't really show why it crashed with this. Something wasn't freed for some reason. Can you still reproduce this? I'd like to know of a way to reproduce this. Maybe you can copy this problematic user's mailboxes to a test user and keep deleting stuff until you see what triggers it?

I started removing files as you've suggested and the minimal condition that triggers a crash is at least one non-mbox file.

$ rm /var/mail/user
$ rm -rf ~user/mail/*
$ echo x >~user/mail/x

$ doveadm mailbox status -u user messages \*
doveadm(user): Error: Syncing mailbox x failed: Mailbox isn't a valid mbox file
