Comment 8 for bug 867753

It appears to be something about the handling of the default language, manually set languages are fine with that plug-in. It would appear that without the GB language pack, Firefox defaults to en-US (ignoring the language set in the OS/desktop), which is not what I'd expect, but never mind. The plug-in developer and I have failed to locate the source code for that language pack and I was hoping you'd be able to point me in the right direction.
