Comment 4 for bug 637692

This is a request for a Feature Freeze Exception, per https://wiki.ubuntu.com/FreezeExceptionProcess#General Instructions

Change description: The change is to allow applications using a particular kind of dynamic menus, like Shotwell, to have their menus properly exposed on the new panel menu.
Rationale for the exception: Without the change, all of Shotwell's menus are displayed and active, whereas only a few of them should be present. Without the change, the UI of Shotwell is severely impacted. Shotwell is the default photo management application for Ubuntu Maverick.
Additional information: the change requires fixes in several packages like unity, dbusmenu or libindicator; the libindicator change creates an ABI incompatibility as we ran out of free function slots in the object interface; this change in turns requires a rebuild of all indicators (~25) but not applications using the app-indicator protocol.
