 A Bitmap instance is being created with a Height = 0, which generates
 the exception. I'm taking a deep look into the ReportBuilderCode, to
 catch the error.

+Ok, the problem appears to be directly related to DataGrid.DataSource.
+When DataGRid.BeginInit () is invoked and then DataGrid.DataSource is
+assigned, it will remain with the previous value until
+DataGrid.EndInit () is called, and DataSource gets a refresh. In .Net,
+even when EndInit hasn't been called, DataSource acquires the new value.
+
+Now, I don't know enough about DataGrid, and probably this is a bad
+practice (to call EndInit without calling EndInit), but I think we
+have to solve this issue anyway.
+
+(The attached sample should print a value different than "null").
