odd… never seen that error before...  Do you have a DNSBL Group with only a customlist defined? IE: no Source URLs being used?

Can you run this command and post the result:
(Change "EXAMPLE" to the name of this DNSBL Group)

grep -A30 ">EXAMPLE<" /conf/config.xml

You can try to open and save that DNSBL Group and see if it fixes it.

To patch the pfblockerng.inc file (if your comfortable in editing the file):

/usr/local/pkg/pfblockerng/pfblockerng.inc
Edit Line 3205

From:

if (empty($list['row'][0]['url'])) {

To:

if (isset($list['row']) && empty($list['row'][0]['url'])) {
