GAE的第三方上传工具SDUpload 的ERROR sdappcfg.pyo:1334 An unexpected error occurred 问题

在使用 SDUpload 上传的时候会产生如下的错误：

2009-08-04 13:51:13,026 ERROR sdappcfg.pyo:1334 An unexpected error occurred. Ab
orting.
Traceback (most recent call last):

其实这是因为网络不通（有防火墙阻拦）的原因。需要使用代理，或者找一台能直接连上 gae 服务器的机器来上传。（gae服务器还没有被墙，不过有些地方的企业防火墙[使用白名单的策略的]会阻拦。）
