Comment:

 The code for LBFGSB has not been changed between 0.8.0 and 0.9.0rc*. It
 seems rather unlikely that the problem is in Scipy.

 Perhaps you should look for the error from the use of Python 2.7 and NLTK.
 The traceback points to the direction that some non-Scipy Python code does
 not function as intended.

 In any case more information is needed.

 (i) What's on the other end of the tracebacks. In particular, cut out only
 the repeating parts and look up where from the code ends up inside
 deepcopy.

 (ii) Can you provide a self-contained script (+ any data required)
 producing the error?
