title: "Unexpected. Please try again." error when performing simple query
body: <p>I keep receiving a status 500 error: "Unexpected. Please try again" message when I perform a query using the Ruby client. This query works when I input this into the API explorer on the google site.</p>
  
  <p>Here is the code: </p>
  
  <pre><code>result = client.execute(
    :api_method =&gt; bigquery.jobs.query,
    :parameters =&gt; {"projectId" =&gt; "projectId"},
    :body_object =&gt; { "kind" =&gt; "bigquery#queryRequest", "query" =&gt; "SELECT date FROM
    [google.com:adsense-reports:Reports.DailyAdUnitReport] WHERE date = CURRENT_DATE()"}
    ) 
  </code></pre>
  
  <p>Is there an error in this syntax? </p>
