Failing unit test

[artivis]

A unit test is failing (rather rarely) with the following,

manif/test/so3/../common_tester.h:982: Failure
Value of: manif::isManifNear(state_pert, state_lin, "state_pert", "state_lin", tol_)
  Actual: false (state_pert != state_lin

This concerns both SO3f & SO3d.

Seeing how state_pert and state_lin are pretty much appart by a factor -1, there might be an angle issue somewhere.
