ofxOscParameterSync crashes on exit

Mac 10.8, Xcode 5.01

Running the oscParametersSender or oscParametersReceiver example and exiting the app causes an Poco exception in ~ofxOscParameterSync when it goes to remove the listener

removing the ofRemoveListener... allows the app to exit cleanly

Start with ofxOscParameterSync.cpp, especially the destructor and its ofRemoveListener call shown in the backtrace. Reproduce the crash by running the oscParametersSender or oscParametersReceiver example on the reported Mac setup, then verify that exiting completes cleanly without the Poco exception.
