[Duplicity-talk] Error when using cleanup on 0.4.6 S3?

[Steve Wuerthele]

I'm trying to use cleanup for the first time, and ran into the following problem.  The error is preceded by a listing of signature files.

Warning, found incomplete backup sets, probably left from aborted session
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 421, in ?
    if __name__ == "__main__": main()
  File "/usr/bin/duplicity", line 405, in main
    elif action == "cleanup": cleanup(col_stats)
  File "/usr/bin/duplicity", line 302, in cleanup
    col_stats.backend.delete(extraneous)
  File "/usr/lib/python2.4/site-packages/duplicity/backends.py", line 776, in delete
    log.Log("Deleted %s/%s" % (
self.straight_url, filename, filename), 9)
TypeError: not all arguments converted during string formatting

I'm running 0.4.6, installed via duplicity-0.4.6-0.fdr.6.i386.rpm, connected to the S3 backend.  Fedora 
2.6.22.9-61.fc6

Any thoughts on what my problem might be?
