Uninformative exception on pushing to repo

[rchl]

I can clone newly created repo. I've also created a commit and tried to push but getting this:

% g push origin HEAD:test
Counting objects: 3, done.
Writing objects: 100% (3/3), 233 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
remote: An exception was raised while processing the request.  A message has
remote: been sent to the system administrator(s).
To xxx.xxx.xxx:/var/git/test.git
 ! [remote rejected] HEAD -> test (pre-receive hook declined)
error: failed to push some refs to 'xxx.xxx.xxx:/var/git/test.git'

In the log I see this:

Request:
{
  "repository_name": "test",
  "refs": [
    {
      "new_sha1": "cff12eff12a224e8f0aa33d78ae119067538c1f3",
      "name": "refs/heads/test",
      "old_sha1": "0000000000000000000000000000000000000000"
    }
  ],
  "user_name": "rchlodnicki"
}

Traceback (most recent call last):
  File "background/githook.py", line 111, in <module>

  File "/usr/share/critic/index.py", line 155, in createBranches

  File "/usr/share/critic/gitutils.py", line 259, in fetch
    stdin.write(sha1 + '\n')
IOError: [Errno 32] Broken pipe

Filed this for the record. I'll submit a fix.
