OSPRay throws an exception when "Curves" geometry supplies a tangent buffer not in vec3f format. However, Embree requires this buffer in vec4f format.
vec3f
vec4f
from the Embree docs:
Similarly, the tangent buffer stores the derivative of each control vertex (x, y, z, r order and RTC_FORMAT_FLOAT4 format)

Fixed in release-2.0.x.
