Is there any possibility to assing keyboard shortcut to activate some EOG plugin?

According to Modify Eye-of-Gnome (EoG) keyboard shortcuts - Ask Ubuntu old accels mechanism is disabled, so … any other ways exist?
May be something that can be called from python code of the eog plugin?
Something like «g_signal_connect» to connect keyboard processing, but may be there exists some python example?

Well, if you want to add Spacebar as shortcut, this worked for me in the Python Console:

app=Eog.Application.get_instance()
accels=app.get_accels_for_action("win.go-next")
accels.append('space')
app.set_accels_for_action("win.go-next", accels)

Do note though that some keys like Spacebar or Return may cause conflicts in certain situations like the menus.
