Xml Error Deserializing Object from BOS

your limit

   I received the following exception when trying to execute a query through the BOS:
EntityServerException:
The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://ideablade.com/EntityModel:FetchResult. The InnerException message was 'There was an error deserializing the object . The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.'.  Please see InnerException for more details.

The Query looks like this:

var member = dataset.ExecuteQueryForEntity<Member>((from mem in dataset.Members

    where mem.MemberId == "754402"

    select mem).Include("ActualCoverages")

    .Include("Subaccounts")

    .Include("Subaccounts.TransferLines")

    .Include("Subaccounts.TransferLines.Payment"));

I tried running the query without the .Includes on it and still got the exception, except that instead of getting it when the query was executed, I got it when it tried loading a specific Payment.  The Payment object has an ntext column on it that is over 23,000 bytes long.  Could this be what's causing the exception?

When I remove this column, the query works.  Should this be a limitation of the BOS?
