New Revision: 85958

URL: http://svn.digium.com/view/asterisk?view=rev&rev=85958
Log:
Trying to remove a non-dynamic queue member via dynamic means can lead to some
interesting (read nasty) situations. This patch clears up the issue by making
only dynamic queue members removable via dynamic methods.
