Comment 0 for bug 893688

When attempting to use a custom activation of a lens result in a scope written in python, Unity.ActivationResponse does not work as advertised at https://wiki.ubuntu.com/Unity/Lenses#Handling_Activation, which suggests that the line Unity.ActivationResponse.new(Unity.HandledType.SHOW_DASH) should pass a response to keep the dash open. Instead, an error in generated suggesting that a second argument needs to be passed to the function. On adding a second argument, the error further suggests that it needs to be a string. On using a string, the following error is generated:

TypeError: can't convert return value to desired type
 ../pathtolens/lens.py:100: Warning: g_object_get_qdata: assertion G_IS_OBJECT (object)' failed GObject.MainLoop().run()
 ../pathtolens/lens.py:100: Warning: g_object_set_qdata_full: assertionG_IS_OBJECT (object)' failed GObject.MainLoop().run()
 ../pathtolens/lens.py:100: Warning: g_object_unref: assertion `G_IS_OBJECT (object)' failed GObject.MainLoop().run()

Similar errors are generated when using other "Unity.Handletype"s (although using NOT_HANDLED only produces the TypeError part, not any of the warnings.)
