Nameserver is jammed when publishing using space in the name topic

I accidentally used spaces in the name to the NoisyPublisher, and nameserver was jammed - the nameserver didn't handle this error gently and was not functioning after that - I think a thread was dead....

Instead of `NoisyPublisher("active_fires_postprocessing")` I used `NoisyPublisher("Active Fires Postprocessing")` and that caused nameserver to not respond properly after that
