Crashing on invalid string would be interesting default behavior from a
library (mine did not call abort() but did show the warning). Anyway,
obviously we should not have triggered this in the first place.

The BSS objects were being unregistered twice and the latter time was
after the D-Bus path had already been freed. This should now be fixed
and I also provided bit more complete handling of network objects (the
ones from configuration file were not being registered, but they were
being unregistered).
