Animation event fires three times on the first frame - is this a known issue?

Howdy, I have an animation with an event on the second frame and one on the last frame. The function that the events trigger takes an AnimationEvent as a parameter and prints the time that the event is triggered.

Triggering the animation gives t$$anonymous$$s result:

w$$anonymous$$ch is exactly what I would expect.

What I really want is to have the first event to be on the first frame, but when I move that event onto the first frame (so there is just one event on the first frame and one on the last) I get t$$anonymous$$s result:

As you can see, the function is triggered 4 times. Twice at the beginning, once at the end, and once at the beginning again. I'm not doing anyt$$anonymous$$ng different other than moving the event between the second and first frames and the animation plays normally both times.

Has anyone had the same problem?

The function just looks like t$$anonymous$$s:

 function PrintTime(animEvent : AnimationEvent)
 {
     print(animEvent.time);
 }

Thanks very much,

Romano

edit: I'm using Unity 4.5 and haven't tried using animation events before t$$anonymous$$s.
