Details:

The following relax script demonstrates the problem:

=====
pipe.create('a', 'mf')
pipe.create('b', 'mf')
pipe.delete('b')
state.save('x')
=====


This executes as:

=====
relax> pipe.create(pipe_name='a', pipe_type='mf', bundle=None)

relax> pipe.create(pipe_name='b', pipe_type='mf', bundle=None)

relax> pipe.delete(pipe_name='b')

relax> state.save(state='x', dir=None, compress_type=1, force=False)
Opening the file 'x.bz2' for writing.
RelaxError: No data pipes currently exist.  Please use the pipe.create user
function first.
=====


Although the current pipe is unset, there is still information in the relax
data store which should be saved - the entire of the 'a' data pipe!
