Hmm that is weird.  The backups were from before rdiff-backup made
mirror_metadata files, so that could be part of the problem.  Can you
do an ls -l on the relevant increments and mirror files?  Like for the
home/5229...doc file, could you do a:

ls -l <destdir>/home/5229...doc
ls -l <destdir>/rdiff-backup-data/increments/home/5229...doc*

Also, can you restore the file "manually"?  The current version should
be at <destdir>/home/5229...doc, so just copy that over.  Then there
should be some diffs in the
<destdir>/rdiff-backup-data/increments/home dir, you can unzip those
and apply them with rdiff in reverse chronological order.

So depending on the number of files it may be easier to restore them
"manually" or to use an earlier version.
