array filter with doesConditionWorkWithTrigger does not seem to work on 4.6 or at least not in upgraded installation?
Error in CRM_Civirules_Form_RuleCondition->buildConditionList
Fixed temporarily with replacing
return array_filter($conditions, array($this, 'doesConditionWorkWithTrigger'), ARRAY_FILTER_USE_KEY);
with
return $conditions;
on local installation at AIVL
