Hi everyone,
I posted this question on SO but no joy so far: Kivy property observer objects left behind after ModalView is dismissed
Perhaps naively, I assumed that dismissing an instance of ModalView removes all strong references to it and its children, enabling garbage collector to clean up. This seems to work OK unless a Kivy property is bound to a child of the ModalView instance. In this case, garbage seems to accumulate until program breaks. Should I be explicitly destroying the observers, in which case - how?

Issue now resolved via a workaround (details on SO) but I am inclined to think this is a bug. ModalView's dismiss() method should clean up observers. However cannot check right now if this has been fixed in Kivy 1.10.0 because of problems installing this under Raspbian Jessie 2017-04-10 release.
