It uses the _AKP-language, if not present the NVRAM-language, if not present the OS-language. If the UI-language is changed at runtime, it should always be represented in the _AKP-cookie and everything is o.k.
There was a small possible bug: When no language could be found, the language-value would be an error-code, now it's set to 0.
