This line of code is your problem. +URLWithString: is not an appropriate way to create a URL from a path. +fileURLWithPath:isDirectory: is what you want instead.
+[NSSavePanel setDirectoryURL:] behaves oddly with non-existing paths, as covered at http://www.mikeabdullah.net/pre-populating-nssavepanel.html
