Based on [0], I would say that it is Bobspeak for error :). For those to lazy to look, the first result for "觬巂" in google is this article. Of the remaining first page results, the string "觬巂" never appears.
Based on the article it should mean _something_ in Chinese but you won't fool the Chinese with that and the English wouldn't use Chinese error messages.
I couldn't find any dictionary that could find that word. Google translate lists it as "Nijuan", which I would assume is just Google using a phonetic system on the assumption that it is a name.
