Linkd exception invoking new IpCidrRouteTable scanner

New Linkd's IpCidrRouteTable scanner crashes on Ubuntu 10.04. with the exception shown below.

I noticed that this happens on every Cisco Device in our network matching the initial 'sysoidRootMask=".1.3.6.1.4.1.9"' configuration directive in linkd-configuration.xml. In detail: the device has not to match the "<specific>" oid-appendix for this exception to happen.

This error blocks scanning of any further snmp information through linkd.

Additional information can be supplied as requested.
