After a recursive deletion of IMAP folders some folders are still shown in the view. I suppose that these folders are marked as delete but not removed from the model. Steps to reproduce: 1. Create three test folders (1, 2, 3) in the inbox 2. Copy three mails to all folder 3. Move folder 3 into folder 2 4. Move folder 2 into folder 1 5. Delete folder 1 and subfolders Only folders without subfolders are deleted completely. Other folders are still shown in the view.
