GetJson unable to retrieve list of ints

Using the following code the couchbase .net SDK is unable to retrieve a list of ints from couchbase:

var list = new List<int>()

;
_client.StoreJson(StoreMode.Set, "Test", list);
_client.GetJson<List<int>>( "Test");

We are currently running 1.2.4 and it works fine, all versions after this up to 1.2.9 all throw the following error:
Newtonsoft.Json.JsonReaderException was unhandled
HResult=-2146233088
Message=Could not convert string to integer: id. Path '[0]', line 1, position 5.
