Manually triggered build & build against HEAD fails

[ranjib]

build against PR's works fine, but the builds triggered against merge fails. Also any manually triggered build fail.

I have tried using the upstream github-api thinking this may be a side effect of #5

but still no success.

Configuration used:
private github repo
refspec ; +refs/pull/:refs/remotes/origin/pr/
branches to build :${sha1}

Following is the error messages:
