"Copy Rotation" constraint fails when more than 180deg is rotated in combination with influence other than 1.

In the provided example I used an "influence" of 0.5 to link the rotation of the triangle to the rotation of the empty.
If you rotate the empty (select empty, press r, rotation with your mouse) everything seems to be working fine up to the point where the empty crosses the 180deg, at that moment the triangle makes a jump of 180deg. I experience this behavior is with all objects and all blender versions I tested sofar.
I guess this has something to do with some blender internal -pi to +pi rad rotation ranges.

Thanks and Regards,
Rene
