在Windows 7上升级权限后,Esky冻结了

我把它缩小到这个简单的脚本.它要求升级权限,但要么冻结,要么崩溃下面的堆栈跟踪.

脚本

import esky
import esky.sudo

class MyProgram(object):

    @esky.sudo.allow_from_sudo()
    def do_stuff(self):
        pass


app = MyProgram()

sapp = esky.sudo.SudoProxy(app)

sapp.start()
sapp.do_stuff()
sapp.drop_root()

堆栈跟踪

$python test.py
Traceback (most recent call last):
  File "test.py",line 16,in <module>
    sapp.start()
  File "c:Python27libsite-packageseskysudo__init__.py",line 125,in start
    raise RuntimeError("sudo helper process terminated unexpectedly")
RuntimeError: sudo helper process terminated unexpectedly


$python test.py
Traceback (most recent call last):
  File "test.py",line 140,in start
    self.close()
  File "c:Python27libsite-packageseskysudo__init__.py",line 156,in close
    self.pipe.read()
  File "c:Python27libsite-packageseskysudosudo_base.py",line 123,in read
    raise EOFError
EOFError

有谁知道解决方案,或有任何建议？

使用：

> python 2.7.3
> esky 0.9.7
