Exception in log module

[Sitka Pete]

I'm running duplicity version 0.6.11 with Python 2.6.5 on Ubuntu 10.04

Running
rdiffdir sig pp2 pp2.sig
when pp2.sig already exist, I got the following exception:

Traceback (most recent call last):
  File "/usr/bin/rdiffdir", line 233, in <module>
    main()
  File "/usr/bin/rdiffdir", line 210, in main
    write_sig(file_args[0], get_fileobj(file_args[1], "wb"))
  File "/usr/bin/rdiffdir", line 163, in get_fileobj
    check_does_not_exist(filename)
  File "/usr/bin/rdiffdir", line 121, in check_does_not_exist
    "overwrite." % filename)
TypeError: FatalError() takes at least 2 arguments (1 given)

I fixed the problem changing the line 184 of module log.py
from
def FatalError(s, code, extra=None):
to
def FatalError(s, code=ERROR, extra=None):

From a quick view FatalError is used erroneously also in other parts of the code, so the above code fix them all.
