can't restore preferences from backup

[GoogleCodeExporter]

What steps will reproduce the problem?
1. copy jp.tmkk.XLD.plist from backup to ~/Library/Preferences/
2. start XLD.app
3. look at preferences/profiles

How about the reproducibility (always, sometimes, rarely, ...)?
always

What is the expected output? What do you see instead?
The old preferences are not restored. New changes are properly saved 
(destination folder, new profiles) and even if I `rm 
~/Library/Preferences/jp.tmkk.XLD.plist´ the file magically reappears, copied 
from some other place. Looking at the folder during XLD startup i can see the 
backup file being overwritten by this new file.

What version of the product are you using? On what operating system?
Version 20141129 (148.1) on OS X Yosemite 10.10.2

Please provide any additional information below.
I now this is similar to issues 165 and 178 but I checked and the folder 
doesn't have such jp.tmkk.XLD.plist.lockfile. I also checked the backup file 
permissions, nothing wrong.
Also I noticed something strange is happening from the Console app, I append 
the logs:

gestaltSystemVersion is returning 10.9.2 instead of 10.10.2. Use

Don't you have running XLD when you copy .plist? XLD doesn't quit even if you 
close all windows.
