Running some more tests confirms that

1) mailman indeed removes entries from the Cc: address list, if
   these refer to subscribers _and_ these have the "nodupes" flag

2) unsetting the "nodupes" option makes the problem go away.

The statement in [1] suggests that this is considered "intentional
by design", though I cannot follow the argument that otherwise Cc:
lists would grow in long threads.  Apparently there are many
different opinions, see for example [3].

The code snippet given in the original bug description [2] is still
about the same in the version of mailman which we are running
(v2.1.26) so it should be easy to remove the responsible "else"

So an easy work around for the problem is to clear the "nodupes"
setting in your subscription - alternatively we can try and patch
mailman to behave like we want it.

What do you think should we do?
