This can happen if the "Sent" folder was removed via IMAP but its subfolders were
not.  "Sent" becomes another regular directory that happens to contain mail folders
beneath it, but isn't itself a mail folder.  Most every MUA when asked to delete a
folder will recursively delete all of the folder's contents as well, but some do
not.  You can test this by creating a new mail folder, creating a subfolder, then
using cyradm to delete the parent mailbox.  If you then list the mailboxes, you'll
see that the parent is gone, but its children still exist.  At that point the parent
directory in the file system will lack the cyrus.* files, but the subdirectories
will still have them.  I remember having to patch an old version of IMP to
recursively delete a folder's contents so that users didn't end up in this situation
because it seems to confuse the heck out of Outlook 2000 at least.

Of course this may not be your issue at all, but it's one possible explanation...
