navtopology ValueError: need more than 1 value to unpack

[Morten Brekkevold]

In NAV 3.11.0, several users report the following error message intermittently in their cron mail:

Traceback (most recent call last):

The problem here seems to be that the new camlogger has in fact created adjacency candidates that point to themselves. I.e. netbox A claims that one possible neighbor on port X is itself.
