Safari :: Search Bar Now GREEK?

Ever since I upgraded to 10.7.4 I've had some major annoyances rear their heads with my 2011 iMac. The issue I'm looking for help with, though it may seem small, is with the Safari search bar. I know there have been discussions before about this and I've always had a difficult relationship with the search bar as it is supposed to change to your 'local' search engine, e.g. for me that would be Google UK, yet it has often defaulted to Google US which means that searches can be a little less relevant at times. Anyway, for months things have been fine. The search bar defaulted to Google UK until the 10.7.4 update hit... All of a sudden my Google search bar now defaults to Google.com in GREEK... 

Since I don't speak a word of Greek, I'm sure you can see how this has become an issue. I've tried all manner of things, resetting safari, changing language settings but have been unable to get it to change back. I tried changing to Bing search but to be honest, Google search in Greek is a **** of a lot more useful than Bing in English is, which I think says a lot. I did have greek as a secondary keyboard layout so that I could use the greek characters for my physics work but UK English has always been my default and I have since removed Greek yet the search bar stays the same. It's really becoming irritating now as every time I search it sets my whole Google experience to Greek with a cookie so any google.com service I use ends up in Greek and it's a pain to reset it.
