The special folders [Sent] & [Draft] have stop showing up in one of 5 IMAP accounts configuration after a recent upgrade. The [Delete] folder is still there. The underlying IMAP folders are working fine and can be added to the account pane in normal "plain" sync mode. The menu items for the sync pane (<account> -> Options and folders -> Folders) "Sync with [ Drafts ] folder" and " Sync with [ Sent ] folder" do not show up in the problematic account, but do normally show up in the other 4 accounts.
Is this a known bug?
