[Dovecot] Dovecot 2.0.5 crash when It cannot remove maildir

[Len7hir]

This is scenario that cause segmentation fault in my Dovecot.
Maybe I do something wrong, but I don't know what...


We run: mailbox_delete
mailbox_delete do: mailbox_open(box) < 0
and after we have: box->v.delete(box) which run index_storage_mailbox_delete

index_storage_mailbox_delete do:
mailbox_close(box); and now mailbox is closed
(this close box->view and mailbox open)

Try to delete folder, but can't do this... example becaus it is system 
folder, or NFS failure... set error message and return -1.

Now we are returning to mailbox_delete.

And we have:
if (ret < 0 && box->marked_deleted) and this is true
	mailbox_mark_index_deleted(box, FALSE)
		if (box->marked_deleted && del) this is false
		mail_index_transaction_begin(box->view, trans_flags);
			mail_index_view_ref(view)
			and segmentation fault, because view is 0x0
