Query Builder fails to create correctly the schema model

When using specific tables the query builder of the Standalone designer may fail with the message:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Reporting.Design.QueryDesigner.Form.DataModelManager.CreateEntity(String path)
   at Telerik.Reporting.Design.QueryDesigner.Form.DataModelManager.FindOrCreateEntity(String path, Boolean refreshRelations)
   at Telerik.Reporting.Design.QueryDesigner.Form.DataModelManager.AddProperty(Property sourceProperty)
   at Telerik.Reporting.Design.QueryDesigner.Form.DataModelTreeViewController.TreeViewAfterCheck(Object sender, TreeViewEventArgs e)
   at System.Windows.Forms.TreeView.OnAfterCheck(TreeViewEventArgs e)
   at System.Windows.Forms.TreeView.WndProc(Message& m)
   at Telerik.Reporting.Design.Common.Controls.TreeViewEx.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

The SQL script for creating the table to reproduce the issue is given in the Object Reference error on using Query Designer forum post.
