Hi - 

Thanks for the report! After investigating the files you sent, I can confirm that there is a bug in dnsruby which caused this issue. This bug is fixed in dnsruby svn r443, and will be available in the next dnsruby release (which will be required by the next OpenDNSSEC beta).

Thanks, and apologies,


Alex.
