Take a look at
this thread.
Do you have HP software installed?
I am not entirely sure about the explanation in that thread. I do have HP software installed but I don't seem to have pipedaemon. It is possible, however, that it is something HP uses on certain machines or with some software but not others?

Update: see
HP's site for possible information. It seems to have something to do with HP printing in Classic on 10.2/10.3.
