Dovecot most likely saw :2, and :2,S and renamed the :2, one.

I've no idea why you get directories there in the first place though.
How often does the directory pop up there? I'd guess some kind of a
misconfiguration.

What OS and filesystem are you using? Is it possible to create
directories with empty names there? It really sounds like Dovecot sees
an empty directory in new/ and then renames it to :2, in cur/. But what
creates it into new/ in the first place, I've no idea.
