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:

}}}

The 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}}}.

My local fix was to change line 34 in {{{privatetickets/policy.py}}} to:
{{{
(perm and 'TRAC_ADMIN' in perm)
}}}

Once 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
