Does GtkAboutDialog crashes when trying to show for the second time - c

Question

I am using a GtkAboutDialog to open on a button click. It works fine on the first click but on the second click it just crashes. On the button clicked signal I am just using gtk_widget_show() to display the dialog. The about dialog is described in a .ui file

I am retrieving the GtkAboutDialog described there with a GtkBuilder object and assigning it to a pointer for which I am calling gtk_widget_show(). I am not sure why this happens. I have not defined any signals for destroying the object.
C code:
I am retrieving the object this way where main_wind_ob->pmenu_builder is the GtkBuilder object associated with the .ui file mentioned above.
main_wind_ob->about_dialog = GTK_WIDGET
(
gtk_builder_get_object
(
main_wind_ob->pmenu_builder,
"about_warehouse_dialog"
)
);
Here is the button clicked signal which is supposed to show the dialog.
static void
on_pmenu_about_dialog_clicked(GtkButton * button,
gpointer userdata)
{
#ifdef DEBUG
printf("\non_pmenu_about_dialog_clicked()\n");
#endif
mainwindow * main_wind = MAIN_WINDOW(userdata);
gtk_widget_show(main_wind->about_dialog);
}
