Could you please spot where is the fault in this reasoning? I suspect that some of the relations may not be applicable and needs to be substituted with something else (or I'm just making a gross mistake as usual...):
Speed of light in a material:
[tex]c=\sqrt{\frac{1}{\epsilon\mu}}[/tex]
where permettivity is
[tex]\mu=\mu_r\mu_0[/tex]
and suscettivity is
[tex]\chi_m=\mu_r - 1[/tex]
which describes the magnetization of the material due to an external magnetic field
[tex]M=\chi_m H[/tex]
-------------------------
A superconductor behaves like a perfectly diamagnetic material, suppressing the internal field B because
[tex]\chi_m = - 1[/tex]
[tex]M=-H[/tex]
therefore
[tex]\mu_r = 0[/tex]
[tex]\mu = 0[/tex]
[tex]c=infinite[/tex]
which clearly makes no sense...
