Description (last modified by Antoine Martin)

ie, on a system where avahi was not started? (or was the port blocked?), this error occurred (which is obscure to say the least):

Exception in thread avahi_publisher for: [('0.0.0.0', 35941)]:

This could also be a threading / locking issue I do not understand , here are some more errors:
