title: Golang CSV error bare " in non-quoted-field
body: <p>I haven't had trouble parsing csv files for my GAE golang app until this week (I updated to appengine 1.9.23 last week).  Now, regardless of file content I am getting this error:</p>
  
  <p>2015/07/09 15:25:34 http: panic serving 127.0.0.1:50352: line 1, column 22: bare " in non-quoted-field</p>
  
  <p>Even when the file content doesn't contain any " characters at all the error occurs.  </p>
  
  <p>Anyone know why my files can no longer be parsed?  Something changed or I'm doing something super-stupid.  </p>
  
  <p>PS using urlfetch to obtain the csv file</p>
