The CRL is being constructed from a fuzzed data input stream. All I know is that the name in the CertificateIssuerExtension looks like an x509.OIDName in the first test, and in the second test it looks like an x509.X400Address.

I can add these two comments to the test:
"Fuzzed data input stream looks like an x509.OIDName." and
"Fuzzed data input stream looks like an x509.X400Address.".
