EF 5 Migration Update-Database Failing When Navigation Property Added

I am using EF5 with Code First with MVC4 in VS2010.

For models, I have a ChargeTransaction model and a ChargeError model. ChargeTransactions -> ChargeError is a 1-M relationship.

Here are the model classes

[Table("ChargeTransaction")]
    public class ChargeTransaction
    {
        public int Id { get; set; }
        public int AccountId { get; set; }
        public DateTime Created { get; set; }

        public virtual Account Account { get; set; }
    }

    [Table("ChargeError")]
    public class ChargeError
    {        
        public int Id { get; set; }
        public int ChargeTransactionId { get; set; }

        // adding this line breaks update-database
        public virtual ChargeTransaction ChargeTransaction {get;set;}
    }

When I add the ChargeTransaction navigation property to ChargeError and add a migration and then call update-database, I get the following error:

Target database is: 'ChargesInterfaceDashboard' (DataSource: localhost, Provider: System.Data.SqlClient, Origin: Configuration).
Applying code-based migrations: [201310282228417_stuff 2].

I have navigation properties between other tables (for example in ChargeTransaction I have a navigation property for the Account table) and they migrated fine.

Any ideas?

The issue was that I had data in the ChargeError table that had 0 in the ChargeTransactionId, and there are no rows in ChargeTransaction, so there are no rows in ChargeTransaction with an Id=0.

Once I deleted all rows in ChargeError, the update proceeded as normal.
