Resolved by waiting for IPv6 DAD to complete in scripts/vyatta-dhcpv6-client.pl. The 'configure failed!' message no longer appears, dhclient starts and the configuration nodes are not deleted.
Typically it only has to wait 1 second for DAD to complete, so on some systems/reboots you would never have seen this issue.

From this report, the issue is in ifupdown and is supposedly fixed in 0.8.11. Unfortunately, this version is not available in Jessie without resorting to backports.
Some further investigation:
