[Dovecot] Maildir + Evolution

I don't know if this is an Evolution bug or not, but when I use the maildir format with Dovecot 0.99.10p2 (from OpenBSD packages collection)
and connect to it from Evolution 1.4 using IMAP, Evolution displays subfolders incorrectly. It actually does not show any subfolders, only root folders with names like "Folder.Subfolder" and "Folder.Subfolder.Subsubfolder". There's no such problem when using traditional mailboxes. Is this an Evolution bug or one of Dovecot's? I had thought the IMAP protocol should act the same no matter which mail dir structure was used...
