workitem.open() KeyNotFoundException TFS 2013

I'm stuck with this exception "The given key was not present in the dictionary" which indicates that some value was not found in the dictionary, but the strange thing is I'm not using any dictionary, I guess it is some internal code of the TFS API of C#. Here is the part of the code raising the exception :

if (wi.Validate().Count == 0)
{
     // Save the work item to submit changes
     wi.Save();
}
else
{
     Console.WriteLine("following errors was encountered when trying to save the work          item {0} : ", id);
     foreach (var e in wi.Validate())
                        {
           Console.WriteLine(" - '{0} '", e);
     }
}


                    // Close the work item
                    wi.Close(); 

                    // Submit the changes to the database
                    SubmitChangesToDatabase(id, author, statusChanged, previousChangeTime);  

                    // Open again the work item to go on with other updates
                    wi.Open();

This code is a part of loop, where I get the work item, perform some updates using the TFS API, after that, I change the read-only fields directly on the database using the method SubmitChangesToDatabase. The exception is raised when invoking the method Open(). The stack trace is as follows :

I have had this before when my Team Project is configured to use Team Field instead of Aeea Path. If you changed this and some of the work items do not yet have a Team specified then you will get this error.

If you create a query with "yourteamfield.team" set to empty and bulk update all of the work items to have a value the error should go away.
