cg-clone failing to get cogito latest tree.

On a new machine, trying to boostrap into latest cogito, I download and make cogito 0.12.1, and then...

$ cg-clone http://www.kernel.org/pub/scm/cogito/cogito.git cogito defaulting to local storage area 14:48:53 URL:http://www.kernel.org/pub/scm/cogito/cogito.git/refs/heads/master [41/41] -> "refs/heads/origin" [1] progress: 34 objects, 45126 bytes error: File d2072194059c65f92487c84c53b9f6b5da780d14 (http://www.kernel.org/pub/scm/cogito/cogito.git/objects/d2/072194059c65f92487c84c53b9f6b5da780d14) corrupt

Cannot obtain needed blob d2072194059c65f92487c84c53b9f6b5da780d14 while processing commit 0000000000000000000000000000000000000000. cg-pull: objects pull failed cg-init: pull failed

any hints? I have a similar problem fetching git with cg-clone: 

$ cg-clone http://www.kernel.org/pub/scm/git/git.git git defaulting to local storage area 14:53:44 URL:http://www.kernel.org/pub/scm/git/git.git/refs/heads/master [41/41] -> "refs/heads/origin" [1] progress: 2 objects, 4666 bytes error: File 6ff87c4664981e4397625791c8ea3bbb5f2279a3 (http://www.kernel.org/pub/scm/git/git.git/objects/6f/f87c4664981e4397625791c8ea3bbb5f2279a3) corrupt

Probably doing somethginf hopelessly wrong...
