Actually I think that my analysis was a bit wrong. I switched to the
latest source 0.4.4RC4, cleaned up one of the failing backup directories
and attempted to run a new incremental backup.Just to be paranoid I
checked the collection-status afterward. It wasn't good. I've included
the entire output from the command below, but notice:

    Added incremental Backupset (start_time: Sat Nov  3 02:50:55 2007 / 
end_time: Sun Nov  4 01:54:14 2007)
    Ignoring incremental Backupset (start_time: Sun Nov  4 01:54:14 2007; 
needed: Sun Nov  4 01:54:14 2007)
      

I'm in the E[SD]T timezone, and 11/4 was the day that the time changed.
I noticed that there are some other messages in the archives on 11/5
that refer to collection problems.

The full output from the command is below:
