I'm using maildir (and have been for a long time). Today I have a problem:

What's this? It seems to be causing my mail client (kmail, using dimap), to hang.

That's a mailbox. You can create it with CREATE ";SECTION=" IMAP command, and that's what the client did for some reason. If it hangs kmail, it's a kmail bug (especially if it created it in the first place).
