Check_MK Werk 6173: Fixed possible crash in Check_MK and Check_MK HW/SW Inventory

ID: 6173 Title: Fixed possible crash in Check_MK and Check_MK HW/SW Inventory Component: Core & setup Level: 1 Class: Bug fix Version: 1.6.0i1 When using pretty outdated "Do hardware/software Inventory" rules which have been saved before 1.4, this could lead to crashing Check_MK and Check_MK HW/SW inventory services with errors like this: 'NoneType' object has no attribute 'get' Workaround: Open this ruleset and save the rules in the relevant folders. The configs will then be transformed and rewritten in the current format which prevents this crash.
