Someone has defined a function signal_handler() that takes one argument, and connected it to some signal, but that signal was then received with two arguments. Whatever module defines signal_handler() is probably out of sync with the D-Bus API of whatever module emits the signal.

What else could dbus-python do about this, other than logging a warning and carrying on?

(There's a genuine dbus-python bug here too, which is that it doesn't know the process name, so it can't log it.)
