From Marcin Prus, "some time ago there was an optimization fix including change in DirectionalSector::computeMatrix().

Browse Source 
Rotation matrices were replaced with quaternions but incorrect contructor was used. There was a call to Quat(angle, xAxis, yAxis, zAxis ) but there is no such constructor in Quat class to create quaternion for rotation. As a result we got this values being written into quaternion directly.

I've replaced Quat contructor calls with the ones creating rotation quaternions Quat( angle, Vec3( axis ) )."
