Testing this on the alpha sandbox... the error below occurs if the user has NEITHER 'access CiviMember' NOR 'edit membership' permissions. The bug is: if "access CiviMember is FALSE, then the Membership tab should be suppressed.
With regard to Dave Lange's comment below - the current code does give "view only" access to Membership info for users who have "access CiviMember" permission but do NOT have "edit membership" permission).
— original post —
When a user that does not have the "edit memberships" permission clicks the new "Membership" tab, they receive the following error in the ContentPane:
Error loading 'https://www.domain.com/civicrm/contact/view/membership?reset=1&force=1&snippet=1&cid=4147' (403 OK)
This is rev 7802
