Summary:
The project attach is a sample project to reproduce what we see in our production project.
When doing clean build (build and derived data folder deleted) from the command line, about 50% of the time it will return an error similar too:

/* com.apple.ibtool.errors */
/Users/dogfish2/Desktop/test2/Base.lproj/7.xib: error: The file “ca.lproj” couldn’t be saved in the folder “test2.app” because a file with the same name already exists.
    Failure Reason: A file with the name “ca.lproj” already exists.
    Recovery Suggestion: To save the file, either provide a different name, or move aside or delete the existing file, and try again.
    Underlying Errors:
        Description: The operation couldn’t be completed. File exists
        Failure Reason: File exists

If i use xcodebuild -IDEBuildOperationMaxNumberOfConcurrentCompileTasks=1 then the error never happens

Steps to Reproduce:
- in the terminal change to the directory containing the project
- type xcodebuild

If error has not happened, delete build folder and derived data folder and repeat above step a few times (this reproduce best on a slow machine, i'm using a mac mini late 2012 with 16GB of RAM, 2.3 GHz Intel Core i7,  running yosemite and xcode6.1)

Expected Results:
No error, build succeed

Actual Results:
error is returned for one of the XIB files

/* com.apple.ibtool.errors */

    Recovery Suggestion: To save the file, either provide a different name, or move aside or delete the existing file, and try again.
    Underlying Errors:

        Failure Reason: File exists
