possible error in "create_mesh_from_regions

[Nick]

using the below... eg no interior region defined produces an error

from caching import cache _ = cache(create_mesh_from_regions,

project.polyAll, {'boundary_tags': {'top': [0], 'topleft': [1],

'topleft1': [2], 'bottomleft': [3], 'bottom': [4], 'bottomright': [5], 'topright':[6]},

'maximum_triangle_area': 500, 'filename': meshname}, verbose = True)

following is the error message

Traceback (most recent call last):
