How to find corrupted file for Continous Integration

I found out how to find this file with wrong encoding. I've written simple C# program that uses the same method that CI seems to be using (by looking at stacktrace). It broke just on the corrupted file and I could see it's location.

static void Main(string[] args)
    {
        var path = @"path_to_your_app_data\CIRepository";
        string[] filenames = Directory.GetFiles(path, "*.xml", SearchOption.AllDirectories);
        var document = new XmlDocument();
        foreach (var fileName in filenames)
        {
            document.Load(fileName);
            Console.WriteLine(fileName);
        }
    }

Might be a good suggestion to send Kentico to have this simple checking on the CI module before attempting to process and maybe spit out an event log record on the record(s) that fail.
