actually duplicity should not make such a mess in the first place...

quick question: this looks like an external harddisk, right? are you
certain that you never-ever unplugged that disk before the system buffers
were written out? (also, is write caching enabled for that disk?)

that's the simplest explanation i can think of that would explain 
'some blank files that shouldn't be blank, without anybody noticing'.

to be honest, i'm not sure whether it makes sense to add further complexity 
to duplicity to deal with this very screwed up situation: an unreadable 
manifest might be recovered from the actual backup, sure, but as you 
said some of the actual volumes were also gone...

as a workaround for now i'd move the damaged manifest and volumes to 
a different directory and then retry the restore.
