Comment 11 for bug 720525

When I specify the whole directory that contains the troublesome file, there is no problem either. I've added a few debug messages, and apparently there are three patches for this file:

[(('filelist',) reg), (('filelist',) reg), (('filelist',) reg)]
difftype: snapshot
difftype: diff
difftype: diff
Writing filelist of type reg

However, when I try to restore the whole backup, the snapshot is missing:
[(('.duplicity', 'filelist') reg), (('.duplicity', 'filelist') reg)]
difftype: diff
difftype: diff

I'll have to look into how these patch sequences are being generated to figure out why the snapshot is missing in the second case.
