Does `git cat-file -p <sha1>` show a tree object? FWIW, I expected to see a tree line there, so maybe this object was created without a tree? I also don't see a parent listed.
I did this on one of my repos:
>>> buf = open('.git/objects/cd/da219e4d7beceae55af73c44cb3c9e1ec56802', 'rb').read()
>>> import zlib
>>> zlib.decompress(buf)'commit 246\x00tree 2abfe1a7bedb29672a223a5c5f266b7dc70a8d87\nparent 0636e7ff6b79470b0cd53ceacea88e7796f202ce\nauthor John Szakmeister <john@szakmeister.net> 1369168481 -0400\ncommitter John Szakmeister <john@szakmeister.net> 1369168481 -0400\n\nGot a file listing.\n'
So at least creating the commits with Git, I see a tree. How was the commit you're referencing created? Perhaps something is wrong with that process?

I'd expect that too.
