Crash in NSSavePanel upon clicking a folder/directory - xcode

Question

I built the app with Standard Architectures (64-bit Intel) (x86_64), SDK: Latest OSX (OSX 10.9) and deployment target: 10.8 using Xcode 5.1.1.
Upon Opening NSSavePanel, once the user clicks a folder, the app crashes. Below are the code snippets and the crash log. This issue does not happen in my development macbook (OS: 10.9.5). It just happens in the client's macbook (OS: 10.8.2). I can't run Xcode in my client's macbook by the way.
-(IBAction)onSaveScriptFileAs:(id)sender
{
NSSavePanel *theSavePanel = [NSSavePanel savePanel];
[theSavePanel setTitle:#"Save Test Script As"];
[theSavePanel setAllowedFileTypes:[NSArray arrayWithObject:#"ts"]];
if (tempScriptFileName != nil) {
[theSavePanel setNameFieldStringValue:tempScriptFileName];
}
if ([theSavePanel runModal] == NSFileHandlingPanelOKButton)
{
[self saveScriptFile:[[theSavePanel URL] path]];
[self setTempScriptFileName:nil];
}
}

Thank you!

My only guess is that your using Latest SDK 10.9, and client is running on 10.8.
Try linking with 10.8 SDK and giving that to client.
By the way, I use Xcode 6, but I'm still linking to 10.6 SDK using some trickery.
Must support older clients.
