When did PicklistEntry label become null?

Question

Used this code to get PicklistEnry list from field and get Label from it:

DescribeFieldResult res = Organization.getSObjectType().getDescribe().fields.getMap().get('OrganizationType').getDescribe();

List<PicklistEntry> entries = res.getPicklistValues();
for (PicklistEntry entry : entries) {
    System.debug(entry.getValue() + ' : ' + entry.getLabel());
}

It worked yesterday, but today I'm getting null for labels:

05:56:41.13 (29155386)|USER_DEBUG|[5]|DEBUG|Team Edition : null
05:56:41.13 (29290993)|USER_DEBUG|[5]|DEBUG|Professional Edition : null
05:56:41.13 (29398823)|USER_DEBUG|[5]|DEBUG|Enterprise Edition : null
05:56:41.13 (29535199)|USER_DEBUG|[5]|DEBUG|Developer Edition : null
05:56:41.13 (29681282)|USER_DEBUG|[5]|DEBUG|Personal Edition : null
05:56:41.13 (29809578)|USER_DEBUG|[5]|DEBUG|Unlimited Edition : null
05:56:41.13 (29944321)|USER_DEBUG|[5]|DEBUG|Contact Manager Edition : null
05:56:41.13 (30078120)|USER_DEBUG|[5]|DEBUG|Base Edition : null

The question:

Was there any update that SF released without notification? I have checked OrganizationType from Organization standard object on several orgs, but result is the same.

UPDATE:

I have logged a case (28390515) with SF Support for this issue, will update question soon.

Answer 1

This is almost certainly a bug. Yes, Salesforce does receive occasional mid-cycle patches, which are usually documented (see this question for more info). I would recommend contacting Support to log a bug.

Answer 2

Out of curiosity I also tried to find any other standard picklists with nulls in labels of entries. Apparently, there is a lot of them. Code to try:

for (SObjectType obj : Schema.getGlobalDescribe().values()) {
    DescribeSObjectResult objectResult = obj.getDescribe();
    if (objectResult.isCustom()) continue;
    for (SObjectField field : obj.getDescribe().fields.getMap().values()) {
        DescribeFieldResult fieldResult = field.getDescribe();
        if (fieldResult.isCustom()) continue;
        if (fieldResult.getType() == DisplayType.PICKLIST || fieldResult.getType() == DisplayType.MULTIPICKLIST) {
            List<PicklistEntry> entries = fieldResult.getPicklistValues();
            if (entries != null && entries.size() > 0 && entries[0].getLabel() == null) {
                System.debug(objectResult.getName() + ' : ' + fieldResult.getName());
            }
        }
    }
}

Also I have a response from Salesforce Support:

Based on product team findings label values never existed for OrganizationType picklist as this picklist is only used for internal user or integration purposes.

...

using getlabel function for picklist will be a new feature request for salesforce.
