Remember that Python comes with "battaries included":
#!/usr/bin/env python

from os import walk
from os.path import getctime, join

def cmp_file_by_ctime(file1, file2):
    return cmp(getctime(file1), getctime(file2))

def walktree(path):
    file_list = []
    for root, dirs, files in walk(path):
        file_list += [join(root, file) for file in files]

    file_list.sort(cmp_file_by_ctime)
    return file_list[-2]

HTH,
Miki
