Description Cédric Bellegarde 2014-11-27 15:02:52 UTC 
Hello,

i'm working on lollypop, a pygtk3 software.

I've got a popover containing a stack of GtkScrolledWindow

When calling set_visible_child(), i've got:
Gtk-CRITICAL **: gtk_widget_is_ancestor: assertion 'GTK_IS_WIDGET (widget)' failed

Comes from gtkpopover.c window_focus_in():

focus = gtk_window_get_focus (GTK_WINDOW (widget));

focus is NULL in my case.

It's only happening if i've got this:
- GtkPopover => GtkStack => GtkScrolledWindows => MyWidget

but not if i've got this:
- GtkPopover => GtkScrolledWindow => GtkStack => MyWidgets
