[Users] Snapshot is in old format

[st at overlogic.org]

Hi there!

When I try to make snapshot of my ploop container I have an error:

# vzctl snapshot 2060 --id 6ea44de0-68ff-4044-9264-3dc7e818200d --skip-suspend
Creating snapshot {6ea44de0-68ff-4044-9264-3dc7e818200d}
Storing /vz/private/ploop/2060/Snapshots.xml.tmp
Error in is_old_snapshot_format (snapshot.c:39): Snapshot is in old format
Failed to create snapshot: Error in is_old_snapshot_format (snapshot.c:39): Snapshot is in old format [38]
Failed to create snapshot

It is made by vzctl version 4.6 and runing on vzctl version 4.7.2
