[Duplicity-talk] Restore fails at "cleanup temporary file"

[fmcom]

Newly using duplicity, I attempted an experimental restore operation.
First I renamed a backed-up directory; then attempted to restore the
original from the backup.  This failed with the error message: "Cleanup
of temporary file ... failed."  It's particularly strange in that an
earlier file (in the same directory) was "forgotten".

This is on a Debian testing/lenny system with duplicity 0.4.8.  The
Changelog for the more current 0.4.9 didn't seem to have any item[s]
that I could associate with this error.

Any help for this?  A fuller exposition of events follows:
