Summary
A protected custom setting and batch job working with it are added to a managed package. The package is installed in a subscriber organisation. The batch job is invoked within the subscriber organisation. When the execute method is called, it fails with an internal server error.

Repro
1. In a managed package developer organisation, create a protected list custom setting called 'Setting__c'

2. Create the following post install class to create some dummy data in the setting:

global class PostInstallClass implements InstallHandler {
global void onInstall(InstallContext context) {
Setting__c s=new Setting__c(Name='Test');
insert s;
}
private static testmethod void test1() {
PostInstallClass postinstall = new PostInstallClass();
Test.testInstall(postinstall, null);
}
}

3. Create the following class:

global with sharing class pcsBatch implements Database.Batchable<SObject>
{
global Iterable<sObject> start(Database.BatchableContext batchableContext)
{
return Setting__c.getAll().values();
}

global void execute(Database.BatchableContext batchableContext, List<SObject> scope)
{
delete scope;
}

global void finish(Database.BatchableContext batchableContext)
{
}

private static testmethod void test1(){
Test.StartTest();
database.executeBatch(new pcsBatch(), 1);
Test.StopTest();
pcsBatch p=new pcsBatch();
}
private static testmethod void test2(){
Setting__c st=new Setting__c(Name='TestABC');
insert st;
pcsBatch p=new pcsBatch();
p.execute(null,[select id from setting__c]);
}
}

4. Package up the setting and classes, include the post install script in the package detail, and upload when finished.
5. Install the uploaded package in a separate organisation.
6. Run the following script (replacing the namespace for your own) in the installer org.

Database.executeBatch(new [your namespace].pcsBatch() );

7. Wait until logs for the execute method appear in the console. You will get an internal server error.

Workaround
None
