In case people do keep asking: it is really so, and receivers MUST be able to deal with ACK branch different from branch in INVITE.
that is correct.
The bug report is invalid, ignore it. branch=0 in ACK to a 200 is perfectly valid according to RFC3261.
but i'm not sure that branch=0 would be valid according to rfc3261, which says (section 8.1.1):
The branch parameter value MUST be unique across space and time for all requests sent by the UA.
0 thus hardly qualifies. also
The branch ID inserted by an element compliant with this specification MUST always begin with the characters z9hG4bK.
