Collectd-client.rb error after upgrade to 5.10.1

Since upgrading to version 5.10.1, one of my hosts has been reporting this error when I log in.

ABRT has detected 1 problem(s). For more info run: abrt-cli list --since 1589551501

When I manully try to execute

ruby /var/tmp/one/im/kvm.d/collectd-client.rb kvm /var/lib/one//datastores 4124 60 7 node2

I get:

/var/tmp/one/im/kvm.d/collectd-client.rb:123:in <main>': undefined method split’ for nil:NilClass (NoMethodError)

The opennebula server is not reporting any errors - just this other host. That said all of the VM’s running on this host appear to be working fine.

Any suggestion as to where I should investigate?
