** Description changed:

  This is an existing failure that is uncovered by a new test. Note that
  this failure only occurs with the dgram tests and passes with the
  identical stream and seqpacket tests.
+ 
+ Note that you need a branch of lp:apparmor at r2715 or newer to
+ reproduce this failure.
  
  * The failure:
  
  Error: unix_socket failed. Test 'AF_UNIX pathname socket (dgram); confined server w/ access (rw)' was expected to 'pass'. Reason for failure 'FAIL CLIENT - sendto: Permission denied
  FAIL - recvfrom: Interrupted system call'
  
  * The denial:
