Looks like this is what we see if there are a bundle of errors at very different places, but the main software (NetworkManager) doesn't report them the way it should do -- ignoring some of them, while acting on others, but for none of them giving back useful information.
In my opinion: NetworkManager was a badly written peace of software. -- And this hasn't changed since. But all rely on this stuff, because all concurrent projects have died or are not worked anymore on.
