Well the author at my request was able to remove the call to os.getcwd() which allows the program to operate.
If anyone wants to tinker here is an example that will likely break on someones system. I don't know if this is an LX bug, libc bug, python bug etc. # read a directory, stat all files import os import sys from stat import * def chdir(d): global cwdlist if d != '.': os.chdir(d) if d == '..': cwdlist.pop() else: cwdlist.append(d) print repr('/'.join(cwdlist)) # Comment the line below to allow things to run os.getcwd() def walk(d): chdir(d) dirlist = os.listdir('.') dirlist.sort() for f in dirlist: try: s = os.lstat(f) if S_ISDIR(s.st_mode): walk(f) except OSError, err: print err chdir('..') if len(sys.argv) != 2: print 'need 1 arg, directory to scan' os.chdir(sys.argv[1]) cwd = os.getcwd() cwdlist = cwd.split('/') walk('.')
