Web Audio API Firefox setValueCurveAtTime()

I am crossfading some audio and I have a equal power curve stored in a table. I'm calling this function to start the fadeout. The fade parameter is a GainNode made with createGain()

fade.gain.setValueCurveAtTime(epCurveOut, context.currentTime, fadeTime);

In Chrome and Safari all goes well, but Firefox (v30) complains: SyntaxError: An invalid or illegal string was specified

Instead of context.currentTime I've tried 0 and 0.01. Is this method not implemented maybe? If so how would I alternatively schedule a cosine equal power ramp over time?
