Post receive hook failing

Created by: m4tthumphrey

Since upgrading to 4.0, the post commit hooks are running but when I look in Resque they return this error:

undefined method `id' for nil:NilClass

/home/gitlab/gitlab/app/models/project.rb:104:in `find_with_namespace'
/home/gitlab/gitlab/app/workers/post_receive.rb:9:in `perform'

The arguments for this were:

"repositories/data/repo_name"
"..."
"..."
"refs/heads/develop"
"..."

I'm a bit confused as the repo_path im supplying doesn't (or shouldn't) contain a / so it should never hit project.rb:104....

In my setup the /home/git/repositories is a symlink to /repositories/data, I'm not sure it that is a factor?
