在GAE的问题跟踪器中启动了一个错误。
id=11001同时，该线程上comme＃4中的临时补丁有效。

google\appengine\tools\devappserver2\static_files_handler.py

line 166, 167, 168, need add str to self._get_mime_type(full_path)

if user_headers.Get('Content-type') is None:
    #headers.append(('Content-type', self._get_mime_type(full_path)))<br />
    headers.append(('Content-type', str(self._get_mime_type(full_path))))<br /><br />
