Duplicity: How to list versions of a file?
Solution 1:
Since version 0.7.03 of Duplicity it is possible to list the revisions that a file has changed in:
duplicity collection-status --file-changed 'filename' 'remote-url'
Solution 2:
There was an answer on the mailing list by Edgar Soldin:
no, you can currently list all backed up versions. duplicity will not tell you when they were changed. this could however be implemented as duplicity internally keeps track of that.

So in essence: It is not possible with vanilla duplicity now, but the data is in duplicity metadata.
