I've created an indicator that I think should work, but doesn't. I've added the UI interface from a glade file, loaded it and added the menu to appindicator. The following is the entire source code beginning with the XML. Is there any reason why this shouldn't work?

The problem is that your Indicator object (ind) is not a class variable, it's scope is only in the __init__ function. This means it is being destroyed by Python's garbage collection once your class finishes initation. To fix this, replace ind with self.ind:
self.ind = appindicator.Indicator("jes_test_menu", "indicator-messages", appindicator.CATEGORY_APPLICATION_STATUS)
self.ind.set_status(appindicator.STATUS_ACTIVE)
self.ind.set_attention_icon("new-messages-green")
self.ind.set_menu(menu)
