You need to either

a) Stop the current key_press_event from propagating into the
GtkEntry widget.

b) Use an idle function to return the focus to the widget.

Read the FAQ and tutorial if you have doubts about how to do this.

Your assessment isn't entirely correct. What is happening is that the
focus _is_ being set to the GtkEntry, but right after being shifted to
another widget when the tab is finally received in the widget. Signal
receival order isn't trivial; study it.

Take care,
