Run_simple dev web server from werkzeug does not run using reloader under Windows

I can not run the run_simple dev web server from werkzeug under windows and use_reloader=True :

run_simple("localho开发者_C百科st", 8090, application, use_reloader=True)

Eventually it throws too many values to unpack while traversing new_environ in wergzeug.serving. If I remove use_reloader (defaults to False) than the server runs without problems. What do I miss?

UPDATE: This problem appears only on 0.6 version. (That is, on 0.5 works, on 0.6 it does not. I don't know about the minor revisions.)

Use the development version. The upcoming 0.7 release will fix that.
