xcode - build project - Append stops working when resources folder is present

After using a Resources folder under Assets I cannot append the build anymore, anyone know a workaround for this? Before I used the resource folder the append worked.

Here is the error:

Error building Player: IOException: /Users/michaelvoigt/Desktop/ipad interactive/build/Data/Raw/.DS_Store already exists UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

I have to replace the build every time now and that takes much longer

Have the same problem - did you ever fix?

It appears that unity 3.2 has fixed this.

They didn't list this in the bug-fix list, but I'm not seeing the issue anymore.
