I've checked the file and the first thing to draw my attention was the name of the configuration file. In my case it is called simply 'config' and not 'config.txt'. So, it is possible that the file was completely ignored by the SVN client library.
So, in order to check if that is the case, you may try adding/committing resources using command line tool. If it works, then you may try JavaHL based connector and then SVN Kit connector in order to check if there is a difference or not.
Another way is to use plug-in's functionality:
Window->Preferences->Team->SVN->Properties Configuration->Automatic properties.
