Are you using Chrome? I had the same issue when I tried it. I never found a solution. The problem didn't arise in Firefox or IE, which is part of the reason I dumped Chrome.
Or, are you using the Google toolbar? If so, try to navigate to Google.com from google.co.ma (by clicking the link in the bottom right corner of the google.co.ma home page). Then do any search within google.com. You might find that solves the problem.
