erk, Bug? ( long post )

[Sean Blakey]

I get a different message on my FreeBSD laptop:
OSError: [Errno 2] No such file or directory.

What is happening is that you are using chdir() to move in to each directory you
check, then calling os.listdir() on the relative path from where you started the
script.

I have attatched a modified version of your script that might clarify this.  The
only modification I made was the os.getcwd() call on line 58.

I suggest seeing if you can work without the os.chdir() calls (or maybe seeing
if you can get the job done with os.path.walk()).

The trouble with computers is that they do what you tell them, not what
you want.
