ksba_crl_parse failed: Invalid CRL object

[gnupg at ethen.de]

When dirmngr tries to load 
http://www.rsasecurity.com/products/keon/repository/certificate_status/RSA_Security_2048_v3.CRL 
I get "ksba_crl_parse failed: Invalid CRL object" in the logfile and 
verification failes. Other CRLs are binary, this one starts with "-----BEGIN 
X509 CRL-----".

Is this expected behavior or what can I do to fix it?

Thanks!
