FileWrapper won't work when GZipMiddleware is installed (Django 1.4 and below): https://code.djangoproject.com/ticket/6027

If using GZipMiddleware, a practical solution is to write a subclass of FileWrapper like so:

from wsgiref.util import FileWrapper
class FixedFileWrapper(FileWrapper):
    def __iter__(self):
        self.filelike.seek(0)
        return self

import mimetypes, os
my_file = '/some/path/xy.ext'
response = HttpResponse(FixedFileWrapper(open(my_file, 'rb')), content_type=mimetypes.guess_type(my_file)[0])
response['Content-Length'] = os.path.getsize(my_file)
response['Content-Disposition'] = "attachment; filename=%s" % os.path.basename(my_file)
return response

As of Python 2.5, there's no need to import FileWrapper from Django.
