The "Edit" and "Composers" tabs are not visible when subscribers present

[Marek Kralewski]

After adding a subscriber to a channel, the mentioned tabs are not usable anymore.
I am using dancing 0.9.9 and Plone 4.0.9

I get a javascript warning, that is maybe related to this issue:
reference to undefined property a.result @ https://www.iz3w.org/portal_javascripts/test/jquery-cachekey1928.js:73

I uploaded a screenshot (in german) and marked the places.

A JavaScript _warning_ is unlikely to cause this problem.

You could try and turn portal_javascript's debug mode on, and make sure you use the Firebug console to see if there's any errors when you load the page.

I can reproduce the issue: after adding a subscriber to a new and clean channel the edit and composers tabs are gone. And I have no JS issues.

Tested with Plone 4.1.3 and collective.dancing 0.9.9/0.9.10
