[maemo-developers] GtkWidget's unmap-event not generated [was: overlaid buttons]

[From: Luca Donaggio]

Hi Kyle,

it's not related to your problem, but be aware of this bug [1] when
considering the use cases for your widget.
In short: HildonAppMenu doesn't appear if there's a top level widget around.
