Redundant "Replace existing file" dialogs

This seems to be a platform-dependent issue.

The same issue was not reproducible on Debian Linux (Wheezy).

Also not reproducible on Windows 7.

It's kind of dumb, because the OS X file chooser prompts you if the filename matches exactly, but not if you exclude the extension, so the prompt is sometimes necessary even on OS X. Still, it would be fixable. On Windows and Linux, I use the swing JFileChooser, which behaves more consistently but looks really bad on OS X.
