I am getting some foreign language (Portuguese?) items appearing in my Safari 5.1.5 context menu, when I right-click on an element in a page (see below). My OSX 10.7.3 language is set to English. I have only 2 plugins enabled (AdBlock and UK Search), neither of which has caused problems before or coincided with this appearing.
Why is this happening, and how do I remove or translate these menu entries?
