'Broken pipe' just means the remote closed the connection. It's a pretty
standard error in this context, which the server should handle.

A process normally gets a SIGPIPE which will by default terminate it, which 
is what you want if you have a pipeline'd command whose output is no longer 
required. An example would be checking there is at least one matching file 
somewhere in a directory hierarchy with:
  read -d '' f < <(find /base/dir -type f -name 'foo*' -print0)
  [[ $f ]] || echo 'no foo* files'

-- find will terminate after the first filename has been read.

In this case, signal(SIGPIPE, SIG_IGN) or the equivalent has been called,
which gives EPIPE instead; a process ignoring the signal is supposed to deal 
with the error. So I'd say it's a bug.
