This is related to issue #11426.

Code starting at line 8598:

  complete(
    xhrSuccessStatus[ xhr.status ] || xhr.status,
    xhr.statusText,
    // Support: IE9
    // Accessing binary-data responseText throws an exception
    // (#11426)
    typeof xhr.responseText === "string" ? {
      text: xhr.responseText
    } : undefined,
    xhr.getAllResponseHeaders()
  );

In that ticket, the fix was to throw an exception for IE browsers, however Chrome v36 throws an exception as well when accessing xhr.responseText. I'm not advocating jquery handling binary data, as another ticket left that for the plugins. What I'd like to see is the conditional:

    typeof xhr.responseText === "string" 

changed to something safer:

    (xhr.responseType === "text" && xhr.responseText === "string")

Or something similar, so long as that check doesn't throw an exception. As it is the current state prevents launching the 'complete' callback for any binary data response, even though 'text' is an inessential parameter (defaulted to undefined).

Thanks.
