Yes, my version is 1.1.15 on both sites. 

I have found today that when I have RHEL/Centos 5 on both sites it seems

that errors.

Could it be problem in python versions?

Thanks a lot, after this correction it doesn't stop, but I reveived lot of 
warnings

local site:
CentOS 5, 
python-2.4.3-19.el5, pyxattr-0.2.1-4.el5, pylibacl-0.2.1-6.el5

remote site:
CentOS 4, 
python-2.3.4-14.4.el4_6.1, pyxattr-0.2.1-4.el4, pylibacl-0.2.1-6.el4
