How To Reproduce
Describe any changes done to a clean kernel for this error to occur.

            // Open database (or create if doesn't exist)
            using (var db = new LiteDatabase(@"0:\\System\\Register.db"))
            {
                // Get a collection (or create, if doesn't exist)
                var col = db.GetCollection<Customer>("customers");

                // Create your new customer instance
                var customer = new Customer
                {
                    Name = "John Doe",
                    Phones = new string[] { "8000-0000", "9000-0000" },
                    IsActive = true
                };

                // Insert new customer document (Id will be auto-incremented)
                col.Insert(customer);

                // Update a document inside a collection
                customer.Name = "Jane Doe";

                col.Update(customer);

                // Index document using document Name property
                col.EnsureIndex(x => x.Name);

                // Use LINQ to query documents (filter, sort, transform)
                var results = col.Query()
                    .Where(x => x.Name.StartsWith("J"))
                    .OrderBy(x => x.Name)
                    .Select(x => new { x.Name, NameUpper = x.Name.ToUpper() })
                    .Limit(10)
                    .ToList();

                // Let's create an index in phone numbers (using expression). It's a multikey index
                col.EnsureIndex(x => x.Phones);

                // and now we can query phones
                var r = col.FindOne(x => x.Phones.Contains("8888-5555"));
            }

Model class:

public class Customer
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string[] Phones { get; set; }
    public bool IsActive { get; set; }
}
