why are revision hashes different between "osc log" vs OBS?

When I see a revision hash in OBS, for instance “93f6a927a5c0a69e4f9ceb30b562af15” here for revision “1” :


it is different than the hash I see when I run “osc log | tail” from the command line:

r1 | castedo | 2013-11-19 20:17:53 | 8b5b14163b225001ded016eccae21dc3 | unknown |

osc --version

Are these hashes supposed to be the same thing? If not, how can I see the hash that appears on OBS from the osc tool? The hash on OBS seems to be the one inside the baserev XML attribute inside _link files.
