Running cmk -U or updating the core configuration crashed with a TypeError when an "SNMP OID range limit" rule had the option "Fetch all available sub OIDs" selected. This default option stores no explicit range limits, but the configuration parser attempted to iterate over the absent value, causing a crash during helper config creation.

Starting with this release, the parser correctly skips rules that have no range limits configured, and configuration generation completes successfully regardless of which option is selected in the rule.
