RE: Wierd traceback on update [patch does not work]

After applying the patch Hunter sent out I still get:

Traceback (innermost last):
  File "/usr/sbin/cadmin", line 325, in ?
    main()
  File "/usr/sbin/cadmin", line 260, in main
    mychan.update()
  File "/usr/share/current/channel.py", line 182, in update
    self._addRpmDir(dir)
  File "/usr/share/current/channel.py", line 624, in _addRpmDir
    self._addRpmPackage(pathname)
  File "/usr/share/current/channel.py", line 850, in _addRpmPackage
    os.symlink(pathname, linkname)
OSError: [Errno 17] File exists

I could not find the second not...tried taking out the first one, same
error.

"It is from numberless diverse acts of courage and belief that human
history is shaped. Each time a man stands up for an ideal, or acts to
improve the lot of others, or strikes out against injustice, he sends
forth a tiny ripple of hope, and crossing each other from a million
different centers of energy and daring those ripples build a current
which can weep down the mightiest walls of oppression and injustice." -

Rackem frackem strackem.

Apply the following patch to the channel.py file.

patch < name_of_patch

If it works, please confirm that it does to the list.
If it doesn't, try taking out the second "not" in the line.

If a couple people (or john) report sucess with this patch, I'll roll it
into 1.4.3
