Profile uses insanely tight-fitting splines. In my experience, you just have to really wail on it.
I'm not sure why Profile insists on making us suffer like this. I've used slip-fit splines to transmit more torque than my (or your) legs can produce without issue. Perhaps the tiny teeth on a 48T spline?
It looks like in the picture the bearings are actually being hammered out of the frame. Try just taking a rubber mallet and pound on one of the arms. Thats how I always remove my profile cranks and never have an issue with it. I am thinking its not so much a spline problem but that the spindle fits to tightly into the bearings.
