Hello,

seems to be a wrong call in /usr/lib64/python2.7/subprocess.py with python-libs-2.7.5-12

New coding:
        try:
            self._execute_child(args, executable, preexec_fn, close_fds,
                                cwd, env, universal_newlines,
                                startupinfo, creationflags, shell, to_close,
                                p2cread, p2cwrite,
                                c2pread, c2pwrite,
                                errread, errwrite)
Old coding:
        try:
            self._execute_child(args, executable, preexec_fn, close_fds,
                                cwd, env, universal_newlines,
                                startupinfo, creationflags, shell,
                                p2cread, p2cwrite,
                                c2pread, c2pwrite,
                                errread, errwrite)

to_close is a new parameter. Going back to old python & libs version fixed it.
