Hi,running 2.4.16 we noticed something that clearly isn't right. Somehow a user managed to rename (or rather move) a folder twice at the same time. The result is an invalid entry in mailboxes.db without the corresponding folder in the file system. Here's what happened:

The relevant part is that one mailbox is renamed twice:Jan 24 18:07:53 clotho imap[3419]: Rename: user.redacted.Archives.Kollegen.Kollegen G&APY-.Henning -> user.redacted.Lehre.1_unerledigt Studies.Kollegen.Kollegen G&APY-.Henning Jan 24 18:07:53 clotho imap[29016]: Rename: user.redacted.Archives.Kollegen.Kollegen G&APY-.Henning -> user.redacted.Kollegen.Kollegen G&APY-.Henning Jan 24 18:07:53 clotho imap[3419]: Deleted mailbox user.redacted.Archives.Kollegen.Kollegen G&APY-.Henning Jan 24 18:07:53 clotho imap[29016]: Deleted mailbox user.redacted.Archives.Kollegen.Kollegen G&APY-.Henning
The first operation succeeded, i.e. the new mailbox exists both in mailboxes.db and in the file system, the second only succeeded partially. So it looks as though there's a locking bug. The client that was used is Thunderbird 17.0.2.
