Feed dialog to event/fan page says "Sorry, something went wrong." after clicking share

Having some issues with the feed dialog when attempting to post to a event or fan page. In my application I am using the JS API and FB.ui using the method feed.

But for a demonstration you can do it using the feed url too for example:

http://www.facebook.com/dialog/feed?app_id=131727613511269&to=287203454659917&redirect_uri=http://www.timeanddate.com/

After clicking share you get the:

Sorry, something went wrong.

We're working on getting this fixed as soon as we can.

Where:

app_id = your app

to = a event / fan page

redirect_uri = a url you are allowed to redirect to

note that the app has publish_stream permissions. (it also has manage_pages for fan pages)

The app in question by the way is: http://apps.facebook.com/tndcountdown/

Thanks,

Andy

EDIT:

An Example taken straight from the documentation:

http://www.facebook.com/dialog/feed?app_id=123050457758183&link=http://developers.facebook.com/docs/reference/dialogs/&picture=http://fbrell.com/f8.jpg&name=Facebook%20Dialogs&caption=Reference%20Documentation&description=Using%20Dialogs%20to%20interact%20with%20users.&message=Facebook%20Dialogs%20are%20so%20easy!&redirect_uri=http://www.example.com/response&to=287203454659917

just replace to=287203454659917 with an event.. (make a test one like it did there)
