Referring to my earlier posts:

I've dealt with those errors. but now have another.
When my backup scripts starts to backup chosen file, python gave me

I've searched over google, but found only that is bug in Python ( 
http://bugs.python.org/issue4071  - in that issue bug is inside Python 
2.5.2 - i've got ActiveState Active Python with core Python 2.6.2), and 
another  info:   *http://tinyurl.com/lvyn7o  and **http://tinyurl.com/kn49vk

Here's my script code:

*Shouldn't that bug be patched already  :-?
