+ # DIESER KOMMENTAR IST NUTZLOS UND MITTLERWEILE VERALTET! (glaub ich)
+ # BITTE NICHT LESEN!
+ # note: you'll probably run into this assert. if this happens, don't panic!
+ # yes, it's evil. I told you that programming in python is just fun, and
+ # suddently, you have to care about things you don't even know.
+ #
+ # but calm down, the solution is easy, at least on paper:
+ #
+ # Each Component, which is a GUIComponent, owns references to each
+ # instantiated eWidget (namely in screen.data[name]["instance"], in case
+ # you care.)
+ # on deleteGUIscreen, all eWidget *must* (!) be deleted (otherwise,
+ # well, problems appear. I don't want to go into details too much,
+ # but this would be a memory leak anyway.)
+ # The assert beyond checks for that. It asserts that the corresponding
+ # eWidget is about to be removed (i.e., that the refcount becomes 0 after
+ # running deleteGUIscreen).
+ # (You might wonder why the refcount is checked for 2 and not for 1 or 0 -
+ # one reference is still hold by the local variable 'w', another one is
+ # hold be the function argument to sys.getrefcount itself. So only if it's
+ # 2 at this point, the object will be destroyed after leaving deleteGUIscreen.)
+ #
+ # Now, how to fix this problem? You're holding a reference somewhere. (References
+ # can only be hold from Python, as eWidget itself isn't related to the c++
+ # way of having refcounted objects. So it must be in python.)
+ #
+ # It could be possible that you're calling deleteGUIscreen trough a call of
+ # a PSignal. For example, you could try to call screen.doClose() in response
+ # to a Button::click. This will fail. (It wouldn't work anyway, as you would
+ # remove a dialog while running it. It never worked - enigma1 just set a
+ # per-mainloop variable on eWidget::close() to leave the exec()...)
+ # That's why Session supports delayed closes. Just call Session.close() and
+ # it will work.
+ #
+ # Another reason is that you just stored the data["instance"] somewhere. or
+ # added it into a notifier list and didn't removed it.
+ #
+ # If you can't help yourself, just ask me. I'll be glad to help you out.
+ # Sorry for not keeping this code foolproof. I really wanted to archive
+ # that, but here I failed miserably. All I could do was to add this assert.
+# assert sys.getrefcount(w) == 2, "too many refs hold to " + str(w)
