I have seen this as well. For me it has usually resulted in MM showing 
both the "Untitled" name and the intended name in the mailbox list, with 
one or the other bearing a "(failed)" label.

I am not certain of the exact mis-ordering of events but it has 
something to do with MM decomposing the creation, subscription, and 
name-setting of a new mailbox into unrelated events that get done in 
parallel rather than a process that has to be held together as a single 
ordered sequence.

First, use the "Mailbox->Edit IMAP Account..." command to edit your IMAP 
subscriptions. Unsubscribe from any mailboxes in the "failed" state and 
subscribe to any of the new mailboxes that you are not subscribed to. 
Once you've made your subscription list coherent with the existing 
mailbox list, you can change the names as needed.
