Error with chordal axis

[jamiedtor]

When running the chordal axis plug in, I receive a Python error:

plugins\geo_sim_processing\chordal_axis_algorithm.py", line 201, in processAlgorithm for line in centre_lines: UnboundLocalError: local variable 'centre_lines' referenced before assignment

Is this a problem with the script included in the plug-in or is this something that relates to my configuration? The full message is below:
