Using Mac OS X 12.6.8 and Remote Desktop 10.9.2. Beginning two versions back (10.9.0?), copy and paste works for a while after launching RD, but it eventually fails when copying from the remote machine to the local Mac. The failure manifests as a spinning beach ball in the application I'm pasting into. The paste operation eventually times out, but the quickest way to recover is to quit Remote Desktop and start the whole operation over again with the copy.
