Er... quite possibly. Did she get up onto the shrine and sit down?
To confirm: the camera focused on the shrine and the gold character got up onto it, but the player (red) could still be moved?
It's probably a trigger issue (the ending cutscene is actually two-stage; it locks onto the shrine, waits for the gold character to run up onto it and then they should sit down and the camera pans back to an end screen; most likely the gold character's navigation messed up and stopped her just short of the final 'wait for the gold character to stand here' trigger)
Never actually had that happen in testing, I'm afraid :z
