That's interesting. I tried to dig into the problem but yet to find its origin:
* Git shallow clone was quite limited before v1.9. On Alioth we have git
v1.9.1, however.
* Any shallow clone via cgit would fail (e.g. using anonscm.d.o/{cgit,git}/).
* Shallow cloning via SSH (alioth account) would *fail* if the user does not
have write permission into the repository. If the user has write permission
then everything would be OK:
% LC_ALL=C git clone --depth 1 git+ssh://hosiet-gu...@git.debian.org:/git/
webwml/webwml2git.git/
Cloning into 'webwml2git'...
fatal: Unable to create temporary file '/srv/git.debian.org/git/webwml/
webwml2git.git/shallow_DrNR7B': Permission denied
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
% LC_ALL=C git clone --depth 1 git+ssh://hosiet-gu...@git.debian.org:/git/
collab-maint/shadowsocks-libev.git/
Cloning into 'shadowsocks-libev'...

( In the example, I am one of the uploaders of the latter package but I don't
have write permission to webwml).
Really interesting. Seems that shallow cloning would create a temp file inside
the repository. For GitHub they handled it properly, and on Alioth the strict
repo owner limitation made it impossible.
