This is an old question, but it would be nice to see it closed out as answered so I'll give you what I can.

Probably the issue lies in your data. I believe there is an issue when you pass DBNull through WCF in a DataTable. If you convert that value to a true null, it will work.

The other weird solution out there seems to be to make sure your DataTable is named. If it does not hav a name, the WCF serializer chokes.

Those two ideas seem to solve most issues with passing DataTables through WCF. Let me know if it works.
