You are probably accessing the button *after* the dialog is destroyed
and the button happens to be referred by that dialog only (thus
child widgets get destroyed with the dialog). If you want to keep
the button you have to g_object_ref it or make function-2 a signal
handler of the dialog to set some variable.
