RotatingSymmetry90 is aborting when evaluating tensor type for Weyl scalars. It doesn't take into account the ManualCartesian type for example. The attached patch avoids that.

Keyword: RotatingSymmetry90

Comment (by Roland Haas):

ManualCartesian implies a single transformation behaviour for all variables in the group. However for RotatingSymmetry90 there needs to be something like an "x" and a "y" component of the tensor identifyable which ManualCartesian cannot provide.

Potentially this could be made to work for "weylscalars_real" if the identity of the scalars in the group are known (they are in RotatingSymmetry). No ET thorn uses this however. Possibly PsiKadelia would have.
