Bug: Portugal Souvenir Shop

Hello from the USA.
I'm using Windows XP with English subtitles turned on.
When I'm in Portugal, and I right-click on the chocolate bar (after I have given the vendor the magazine), I get this in the English subtitle:
No translation found for key "$$POR9186" in "English".
The game does not crash, it allows me to continue.
