GtkButton problem

["Henrik Grimm" <henrik_grimm hotmail com>]

I wrote some days ago that I had problems with disabling a button in its own 
signal handler. I have done some more testing and its seems like this is the 
case. The following is the test program I used:


#include <gtk/gtk.h>

GtkWidget *button1, *button2, *button3;

static void button1_pressed(GtkButton *button, gpointer data)
{
 gtk_widget_set_sensitive(button1, FALSE);
}

static void button2_pressed(GtkButton *button, gpointer data)
{
 gtk_widget_set_sensitive(button1, TRUE);
}

static void button3_pressed(GtkButton *button, gpointer data)
{
 gtk_widget_set_sensitive(button1, FALSE);
}

int main(int argc, char *argv[])
{
 gtk_init(&argc, &argv);

 GtkWidget *window = gtk_window_new (GTK_WINDOW_DIALOG);

 GtkWidget *vbox = gtk_vbox_new (true, 5);
 gtk_container_add (GTK_CONTAINER (window), vbox);

 button1 = gtk_button_new_with_label("Button 1");
 gtk_container_add(GTK_CONTAINER(vbox), button1);
 gtk_signal_connect (GTK_OBJECT (button1), "pressed", 
GTK_SIGNAL_FUNC(button1_pressed), NULL);

 button2 = gtk_button_new_with_label("Button 2");
 gtk_container_add(GTK_CONTAINER(vbox), button2);
 gtk_signal_connect (GTK_OBJECT (button2), "pressed", 
GTK_SIGNAL_FUNC(button2_pressed), NULL);

 button3 = gtk_button_new_with_label("Button 3");
 gtk_container_add(GTK_CONTAINER(vbox), button3);
 gtk_signal_connect (GTK_OBJECT (button3), "pressed", 
GTK_SIGNAL_FUNC(button3_pressed), NULL);

 gtk_widget_show_all(window);

 gtk_main();

 return 0;
}


When button1 is pressed it disables itself, when button2 is pressed it 
enables button1, and when button3 is pressed it disables button1. When I 
press button2 or button3 it works as expected, but when button1 is pressed 
the interface frezes. The buttons are still exposed (i.e., if a move another 
window over this window and then move it away the buttons are still 
visible), but I can't press any of the buttons. Is this a bug?
