> There is a wrong syntax in exception handling code when raising the "Address
> already in use" error in _proton-c/bindings/python/proton/reactor.py_ (line
> 179):
> {code}
> raise IOError("%s (%s:%s)" % pn_error_text(pn_reactor_error(self._impl)),
> host, port)
> {code}
> Which leads to unexpected TypeError:
