sigsegv caught when I click a button.

[Michael Oswell <oswell mail ocis net>]

Hi.. I appear to be having a problem with the button in gtk.  I only
started programming with it about two days ago, and for seom reason,
whenever I click on a button, it sigsegv's.  I've attached the code
and the machine that I am running on... Any help would be greatly
appreciated.

Here is the machine I am running it on:

# uname -a
OpenBSD envy 2.2 GENERIC#10 i386


-------
Here is the error I get when I run it:

# ./configsys 

** ERROR **: sigsegv caught

-------
Here is the code itself.  I can't find anything blatently wrong with it,
though I have changed the gtk_signal_connect a few times hoping it would
fix the problem.


#include "gtk/gtk.h"

int login (GtkWidget *widget, gpointer *data)
{

}

void destroy (void)
{
  gtk_exit (0);
}

void new_alias(GtkWidget *widget, gpointer *data)
{
   g_print("Clicked on new_alias: %s\n", (char *)data);
}


/******************************/

  gtk_window_set_title(GTK_WINDOW (window), "On Call Internet Services - User Configuration");
  gtk_container_border_width (GTK_CONTAINER (window), 10);
