Observed a panic in reconciler: runtime error: index out of range [1] with length 1

I observed a panic in a prow job that's part of a 4.12.0-0.nightly-2022-10-25-210451 payload.

4.12.0-0.nightly-2022-10-25-210451

It did not happen repeatedly so it's certainly not happening often

1. When I went through the Prow CI jobs of https://gcsweb-qe-private-deck-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/qe-private-deck/logs/periodic-ci-openshift-openshift-tests-private-release-4.12-amd64-nightly-e2e-baremetalds-ipi-ovn-ipv4-p1/1585134306458603520/
2. Downloaded the must-gather file and extracted it, searched panic in namespaces directory,
kewang@kewang-mac 2022-10-27 16:49:55 namespaces]$ grep -nr panic

1. Got a panic error of security-profiles-operator pod log files,
