I have detected a bug of conversion data type in OpenSim.Data.MSSQL.MSSQLInventoryData.addInventoryItem(InventoryItemBase item)
in the GroupOwned field.
My sollution is to change the flield to bit in the table. In the
readInventoryItem(IDataReader reader) change too item.Flags =
(uint) reader["flags"]; to item.Flags = Convert.ToUInt32(reader["flags"]);
Now Inventory runs fine.
