Comment 5 for bug 614413

Another instance of the problem found today:

Build a virtual folder based on an IMAP folder, and do get-new-mail in the IMAP folder. This ends up calling vm-build-virtual-message-list for the virtual folder, which calls vm-visit-folder on the IMAP folder. This tries to present a message, which involves vm-retrieve-real-message-body. Since the folder is still in an inconsistent state, this fails. (In particular, the uid field of the message vector is not defined yet.)
