Line 135:         try:
Line 136:             return int(version)
Line 137:         except ValueError:
Line 138:             self.log.error("Received invalid version value: %s", 
version)
Line 139:             return 0

0 is supposed to be the lowest possible version, reporting the apiVersion at 
all shows it knows about this. Therefore the most possible version in that case 
can be only 0. -1 on the other hand means that it is disabled completely which 
of course can be triggered again, however this will result in some ping pong I 
try to avoid.
