Slide move operation launches an exceptio if a child file is locked for publication

I activated the FileLockOnPublication option in the jahia.properties file. Then I tried to move from /shared/abc to a public user directory a full directory including one locked file already published. This gives me an error within the engine and an exception in the console.

So could we move directories with locked files (as the file will still exists after the move)? And if we want to prevent such an operation, we could at least catch the exception and generate a more readable msg for the end-user.
