[PATCH] net-dbus: Raise exception at 'introspector' if network is lost

I believe they are, but in theory :) The question is, as you said, how
many bindings support it. libdbus, gdbus, dbus-java, dbus-python -
they do. dbus-perl doesn't (good point to do it). We can keep it as is
and start looking for a further problems (there is more than NoReply,
..., codes) or we can implement it as it should be (rely on UnknownXXX
errors, actually only 2 of 3) and die with an exception. I'm sure on
99% it won't break anything, but in case of one we'll reach the author
and ask him improve an implementation. This is the only way (strict
rules) make open-source quality better (especially if you can
contribute and help author, nobody is trying to leave you alone with
your "troubles").
