I created my extension for Magento 1.9.
It works on my localhost.
Packed it using Magento Package Extensions.
Uploaded it to Magento Connect.
Created new empty shop with Magento 1.9.
Install module.
And get these errors:

When I open file Data.php using Sublime Editor on new Magento installation, I see this string at the end of file:

So, question is: what is it and how it happens in my file? Original file hasn't this symbols before installation of extension. When I untar file tarred by Extension Package tool - file is OK.
