Comment 4 for bug 721255

First of all, this is just a warning:

/usr/bin/cmcc:379: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
  print "%s: %s" % (error._dbus_error_name, error.message)

This means that I haven't updated the script's exception handling to the latest python syntax. It doesn't break anything (yet), but I should update the code to the latest syntax anyway.

But this is the real error:

org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

This means that we sent a dbus message to connman but didn't get any reply and hence the timeout. I'm guessing this happens because connman crashes. syslog would be able to confirm this, more info here:

If the bug is seen with connman PPA builds but not with the git version, it makes me suspect that there's a ubuntu specific change which causes the crash. My main suspect is 04-wifi-add-a-disconnected-timer.patch which we have to improve roaming between wifi access points.
