Thanks for reporting. Noticed the master was one behind from my workstation, so pushed it (and at least the above works correctly on my workstation).

P.S I changed in the last release a lot how the tensor types are determined, so hopefully this is the last defect due to that change. Normally the test suit is running fine, just in case you need more examples.
