KeyError: u'name' when creating a ticket

How to Reproduce

I just upgraded to 0.12 to get babel-support. While doing a GET operation on /ticket/3 (creating a ticket), Trac issued an internal error.

Request parameters:

{'id': u'3'}

The function render_ticket_action_control() has been changed lately, and the translations have not yet been updated accordingly. In this case, the string at line 243 was "The owner will change to %(name)s" and has been changed to "The owner will change from %(current_owner)s to %(selected_owner)s".
