Xcode 4: Files get stuck outside of project, unable to be deleted

Question

Lots of my files in my Xcode project get "stuck" outside of my project and I'm unable to delete them. This happens occasionally when creating new files (maybe 50% of the time).

Here's a screenshot of what happens:

Any ideas?

Thanks.

Same problem, solved editing manually the project bundle:

• quit xcode
• right click on "Philly Shows.xcodeproj" and show its content
• same operation on "project.xcworkspace"
• open "contents.xcworkspacedata" with a text editor: you'll find references to your stuck groups and files, remove what you want to remove, basically your file should be something like this:

    <?xml version="1.0" encoding="UTF-8"?>
    <Workspace version = "1.0">
        <FileRef
            location = "self:Philly Shows.xcodeproj">
        </FileRef>
    </Workspace>
