Details:

If the program state is saved, loaded, and then saved again, the following
error occurs:

relax> pipe.create(pipe_name='test', pipe_type='mf')

relax> state.save(state='/home/edward/tmp/tmpxnkhBk', dir_name=None,
force=True, compress_type=1)
Opening the file '/home/edward/tmp/tmpxnkhBk.bz2' for writing.

relax> state.load(state='/home/edward/tmp/tmpxnkhBk', dir_name=None)
Opening the file '/home/edward/tmp/tmpxnkhBk.bz2' for reading.

relax> state.save(state='/home/edward/tmp/tmpxnkhBk', dir_name=None,
force=True, compress_type=1)
Opening the file '/home/edward/tmp/tmpxnkhBk.bz2' for writing.

This has been caught in a new system test.
