Hi everyone,

We are currently trying to migrate our code to production, but this FATAL_ERROR|Internal Salesforce.com Error is stopping us.

Here is the code from the triggers that cause this error.

trigger triggerDNC on Contact (before insert, before update) 
{
	List<Contact> conList = new List<Contact>();
	List<String> accList = new List<String>();
	
	if (Trigger.isInsert)
	{
		for (Contact c : Trigger.new) 
		{
			boolean hasAccount = true;
			if (c.AccountId == null)
			{
				hasAccount = false;
			}
			else
			{
				conList.add(c);
				accList.add(c.AccountId);
			}
		}
		List<Account> checkAccList = new List<Account>();
		if (!accList.isEmpty())
		{
			checkAccList = 
				[SELECT Id, BillingState FROM Account WHERE Id IN :accList]; // this is where the error gets generated from !!!
			for (Account a : checkAccList)
			{
				// do stuff .. doesnt get here
			}
		}
	}
}

trigger LeadConversionTrigger on Lead (after insert,after update) {
    try{
    list<Lead> oldlead= Trigger.old;
    list<Lead> newLead=Trigger.new;       
    Account acc= new Account();
    RecordType rdc= new RecordType();
    rdc=[select Id, name from RecordType where RecordType.Name ='FromWeb' limit 1];
    map<id, id> map_OppCon_id = new map<id, id>();
    for(Lead LeadtoWork: newLead )
    {
        Database.Leadconvert lc= new Database.Leadconvert();
        lc.setLeadId(leadtoWork.Id);
        lc.setOverwriteLeadSource(true);
        lc.setConvertedStatus('Qualified');
        lc.setOpportunityName('Opportunity From Web');
        acc.RecordTypeId=rdc.Id;
        Database.Leadconvertresult lcr = Database.convertLead(lc);
        
        if(lcr.isSuccess())
        {
            // do stuff doesnt get here 
        }
        // do more stuff after, but doesnt get here
    }     
    } catch(Exception e){System.debug('exception is>>>>'+e);}  // goes to here after database.convertLead
}

 And here is the test that fails.

@isTest
private class TriggertestClass {
    static testMethod void myUnitTest() {
        Lead l1= new Lead();
        l1.LastName='lead';
        l1.FirstName='test';
        l1.Company='test comapny';
        l1.Status='Open';
        l1.OwnerId='111111111111111';
        l1.LeadSource='Webdialer';
        insert l1;
    }
}

 Here is the full description of the error from the debug log:
