[Brian Szuter]

New submission from Brian Szuter <Brian.Szuter at gmail.com>:

Python-2.5.2/Python/codecs.c(_PyCodec_Lookup)
Lines 106, 144

PyString_Check() is not called on the result of PyList_GetItem() and the
first parameter of PyList_GetItem() does not have PyList_Check() called
on it.
(See Python-2.5.2/Python/traceback.c(tb_displayline) for a correct
instance of the pattern)
