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
 	doveadm(user): Panic: Trying to deinit storage before freeing its objects
 	doveadm(user): Error: Raw backtrace: 0xff1c296c -> 0xff2a4e20 ->
 		0xff29e5cc -> 0xff2a8784 -> 0xff2a89fc -> 0x168d4 ->
 		0x169e0 -> 0x16ef4 -> 0x1745c -> 0x1cafc -> 0x1629c
