Description of problem:
When pushing any code up to openshift, push is successful with the latest commit on the server. However, when attempting to access the website i.e. http://myapplication-myusername.rhcloud.com. The user sees 503 Service Temporarily Unavailable instead of the actual web page.

git push log shows error: "/var/lib/openshift/xxxxxxxxx//.env/CARTRIDGE_VERSION_2: line 1: 2: command not found". Checked CARTRIDGE_VERSION_2 and found that the file indeed contains only 1 line with one single character, the number "2", in it.

Version-Release number of selected component (if applicable):
Cartridge created with Rails Quickstart

How reproducible:
This happens every time I git push to openshift. I think it happened after the cartridge was updated to version 2.

Steps to Reproduce:
1. Edits any repo file and make a local commit
2. Do git push to ssh://xxxxxx.com/~/git/xxxxxx.git
3. Access via browser: http://myapplication-myusername.rhcloud.com

Actual results:
Git push is successful. The edited files appear on openshift server. However, the website becomes inaccessible with 503 Service Temporarily Unavailable. "git push" log returns the following messages...
