You see, that's already something!
Seriously, replacing "self.window.show()" with
"glib.idle_add(self.window.show)" should now get you done. Or in
alternative replacing
os.system('external_script')
self.window.show()
with
glib.idle_add(self.run_script)
def run_script(self):
subprocess.call(['external_script', 'param'])
self.window.show()
