I checked the py stack leading to this AttributeError, it happens the
fault really is in aptdaemon after all.
[(<frame object at 0x3005200>,

i'm not using network-manager on this box so it's probably the least
tested path (if not the totally untested path). That may explain why
there's only a few dupes, not millions.
While exploring that path, I found the bug:
In aptdaemon, self.netmon is a ProcNetworkMonitor() instance, which is good in
my case, and when called, it properly finds 'online'. The problem seems to be
the missing return value in ProcNetworkMonitor.get_network_state().
it sure fixes this AttributeError for me, but then i'm getting a cryptic
_DefGen_Return raise from the defer module. So more work is needed.
anyway, python-defer should not die the way it does anyway, so its task
here is probably also valid.
