Pickle error, vista 64, 2.61b

[Jules Stevenson]

Hi List,

I'm getting the following error from the pickle module:

F = os.path.join(render_map_path,'sizes.pkl')
Pickle_mat = pickle.load(f)

# ERROR : Traceback (most recent call last):
# File "<Script Block >", line 398, in unity_bake_Execute
# pickle_mat = pickle.load(f)
# File "C:\Python26\Lib\pickle.py", line 1370, in load
# return Unpickler(file).load()
# File "C:\Python26\Lib\pickle.py", line 841, in __init__
# self.readline = file.readline
# AttributeError: 'unicode' object has no attribute 'readline'


The contents of the pickle file look reasonable enough to me and are this:

Any help much appreciated
