8458	PrivateTicketsPlugin is incompatible with TracAnnouncer plugin	robguttman	hasienda	This plugin appears to be incompatible with the TracAnnouncer plugin.  I get this in the {{{trac.log}}} file:\r\n{{{\r\nTraceback (most recent call last):\r\n  File /usr/local/lib/python2.6/dist-packages/TracAnnouncer-0.12.1.dev-py2.6.egg/announcer/api.py, line 539, in _real_send\r\n    sf.filter_subscriptions(evt, subscriptions)\r\n  File /usr/local/lib/python2.6/dist-packages/TracAnnouncer-0.12.1.dev-py2.6.egg/announcer/filters.py, line 67, in filter_subscriptions\r\n    if permsys.check_permission(action, sid):\r\n  File /usr/local/lib/python2.6/dist-packages/Trac-0.12.1-py2.6.egg/trac/perm.py, line 454, in check_permission\r\n    perm)\r\n  File /usr/local/lib/python2.6/dist-packages/TracPrivateTickets-2.0.2-py2.6.egg/privatetickets/policy.py, line 34, in check_permission\r\n    TRAC_ADMIN in perm:\r\nTypeError: argument of type NoneType is not iterable\r\n}}}\r\n\r\nThe problem seems to stem from TracAnnouncer not sending a value for {{{perm}}} which the Trac permission system seems to allow and defaults its value to {{{None}}}.\r\n\r\nMy local fix was to change line 34 in {{{privatetickets/policy.py}}} to:\r\n{{{\r\n(perm and 'TRAC_ADMIN' in perm)\r\n}}}\r\n\r\nOnce patched, the plugin appears to work well on Trac 0.12.	defect	new	high	AnnouncerPlugin	blocker		permission None user cache	hasienda, doki_pen	0.12
