When mythbackend is already running, a "mythbackend --setverbose"
command simply sends the new log options to the running copy.  Which
it did - from your log output above:

  Sent 'SET_VERBOSE http:debug,upnp:debug' message

If you want to set the same options on mythbackend when it starts up,
the option is "--verbose", not "--setverbose".  They take the same
parameters.  If you run "mythbackend --help" and "mythbackend -v
help", you will get a list of the options.
