I had great teeth-gnashing trying to import my mail into KMail2. I eventually 
found that my old maildir tree had collected various dotfiles (.foo) that the 
importer gagged on thinking they were supposed to be mail folders. I'd suggest 
looking for dotfiles that aren't mail folders and deleting them before trying 
to import them.
