[Duplicity-talk] Old signatures not removed by remove-*

[Ed Blackman]

My strategy to keep three months of backups is to run a script daily 
that calls "duplicity incremental --full-if-older-than 30D" followed by 
"duplicity remove-all-but-n-full 3 --force".  For the most part, it's 
working: I accumulate incremental backups for 29 days, then it does a 
full backup, then throws away the oldest full backup and the incremental 
backups between it and the second oldest.

However, I have duplicity-full-signatures and duplicity-new-signatures 
files going back much further than that.  "duplicity cleanup" says:
     Local and Remote metadata are synchronized, no sync needed.
     Last full backup date: Tue Mar  9 04:30:01 2010
     No extraneous files found, nothing deleted in cleanup.

I found the --extra-clean parameter from the discussion at 
http://lists.gnu.org/archive/html/duplicity-talk/2010-02/msg00012.html 
but that doesn't seem to do anything when supplied as a parameter to 
remove-all-but-n-full, and removes current signature files (or seems 
like it would, I didn't use --force) when supplied to cleanup.

How can I get duplicity to remove just the old signatures?

This is duplicity 0.6.06 in Ubuntu 8.04.
