Hi, when opening a page containing a plugin object with gtklauncher, and then closing gtklauncher, I get following assertion: (lt-GtkLauncher:24039): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkWidget' that assertion is triggered in ScrollView::removeChild, when trying to cast GTK_WIDGET (child->gtkWidget())
Created attachment 22625 [details] testcase
This seems to work fine now. Closing.
