The new 2.0 release is expected next week. Please note that VirtualBox 2.0 and following versions will ship the VirtualBox GUI that uses Qt version 4 and therefore you need to update the Qt4 NLS files, not the Qt4 ones. See comment:1 and also make sure you have read the Translating document once more since there are some important updates.
To make it clear and avoid any possible confusion, a new ticket:2018 has been created. Please read the first three comments carefully and direct all further translation activity to that defect.
This defect is closed from now on. Please don't comment on it and don't attach any new files here.
