Wireshark-dev: [Wireshark-dev] Wireshark crash on Windows (latest SVN)

I just built Wireshark after performing a svn update. If Wireshark is the active application (has focus) and you hit <alt><ctl><del> to lock the computer, when you unlock or cancel you will find the Wireshark application has crashed. Seems like the work to change the keyboard input to automatically echo to the display filter window is causing the crash. Note that you don't have to have any files loaded, just launch Wireshark, make sure it's the primary application with focus, then press <alt><ctl><del> on the keyboard.
 
We crash in top_level_key_pressed_cb()
 
******************************************************************
static int
top_level_key_pressed_cb(GtkCTree *ctree _U_, GdkEventKey *event, gpointer user_data _U_)
{
    if (event->keyval == GDK_F8) {
 packet_list_next();
 return TRUE;
    } else if (event->keyval == GDK_F7) {
 packet_list_prev();
 return TRUE;
    } else if (isprint(event->keyval)) {                        <----------------------This is where we crashed.............
 /* Forward the keypress on to the display filter entry */
 if (main_display_filter_widget && !gtk_widget_is_focus(main_display_filter_widget)) {
     gtk_window_set_focus(GTK_WINDOW(top_level), main_display_filter_widget);
            gtk_editable_set_position(GTK_EDITABLE(main_d isplay_filter_widget), -1);
 }
 return FALSE;
    }
    return FALSE;
}
event->keyval == 65513
