Question: Bug in LinearAlgebra:-IsSimilar

Hello,

Does any body know why the following code

A:=Matrix(3, 3, [[-1/23*(14+21*62^(1/2))^(1/3)-31/29/(14+21*62^(1/2))^(1/3)-13/107,0,0],[0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10-1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3)),0],[0,0,1/22*(14+21*62^(1/2))^(1/3)+15/29/(14+21*62^(1/2))^(1/3)-13/10+1/2*I*3^(1/2)*(-1/11*(14+21*62^(1/2))^(1/3)+31/29/(14+21*62^(1/2))^(1/3))]]) ;

with(LinearAlgebra):
IsSimilar(AA,AA);
IsSimilar(AA,AA,output=['C']);

induces an error in Maple 12?

Is there a hope to fix that?

Best Regard
