What I do in these cases is run v.clean with the rmarea option. I choose a threshold about 5X the cell resolution to get rid of any small areas like these. I think it comes from the way r.to.vect works (others with more knowledge might correct me). Any cell which touchs the contiguous area only at one corner is considered a separate polygon, so you end up with some square vector areas of size nsresXewres.
Micha, I'd not used v.clean before so this approach did not occur to me. Works like a charm. Now I have a new tool to apply when the situation comes up again.
