A good place to start unwinding this ball of string might be figuring out why the tests on the Stroh class are failing. These tests draw largely from the textbook by Ting.
Particularly, if we make the usual assertion that the eigenproblem is nontrivial only for the case:
N x = p x
(N - p I) x = 0
det(N - p I) = 0
we find that this test is failing (c.f. test_elastic.test_N_nontrivial )
