python - 更新了 Google App Engine，现在出现错误 TypeError : 'NoneType' object is unsubscriptable

Question

我昨晚更新了 GoogleAppEngineLauncher，现在我收到了这个错误

<type 'exceptions.TypeError'>   Python 2.6.1: /usr/bin/python
Tue Nov 8 09:25:13 2011
A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

 /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver.py in _HandleRequest(self=<google.appengine.tools.dev_appserver.DevAppServerRequestHandler instance at 0x114cef368>)
<type 'exceptions.TypeError'>: 'NoneType' object is unsubscriptable 
      args = ("'NoneType' object is unsubscriptable",) 
      message = "'NoneType' object is unsubscriptable"

有什么想法吗？

如果在 app.yaml 中指定，GAE 使用 Python 2.7.x，否则使用 2.5.x。使用 2.6.x 启动时会出现不可预知的错误。
