Potential bad use of null-like value

[ddylihfq]

A recent Coverity scan found a potential issue in cfg.py:line 2662

On line 2642 there is a null_check: Comparing 'group' to a null-like value implies that 'group' might be null-like.
(if group is None and name in self._groups:)

Then on line 2662, accessing a property of null-like value 'group' is noted.
(group_name = group.name if group else None)

Coverity screen shot attached with clearer detail.

Is this a potential issue or a false positive? If so this would be classed as CWE-476: NULL Pointer Dereference.

No pickup on this yet?

The logic pointed does not look like problems at all to me. To be very honest, checking all results from dumb scan requires effort without much gain and I don't really like the idea of pasting the tool result and asking other people to pay effort to these uncertain results.
