Openshift git push fails without or with jenkins - ruby-on-rails

Question

I:
-do some random changes
-git add them, commit and push
Then, the push goes somewhere like this
Counting objects: 13, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (8/8), done.
Writing objects: 100% (8/8), 825 bytes | 0 bytes/s, done.
Total 8 (delta 6), reused 0 (delta 0)
remote: : command not found
remote: An error occurred executing 'gear prereceive' (exit code: 127)
remote: Error message: CLIENT_ERROR: Failed to execute: 'control stop' for /var/lib/openshift/***/ruby
remote:
remote: For more details about the problem, try running the command again with the '--trace' option.

! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'ssh://***#treasurehunt-arakkun.rhcloud.com/~/git/treasurehunt.git/'
I tried to stop, force-stop, start and restart the app, with those results:
Failed to execute: 'control stop' for /var/lib/openshift/***/ruby< though the app actually Stopped
RESULT:
treasurehunt force stopped
Failed to execute: 'control start' for /var/lib/openshift/***/ruby < though the app actually Started
RESULT:
treasurehunt restarted
Then I created a jenkins app, and added a Jenkins client to the main app.
I do the same(random changes, add, commit, push), then it answer:
Counting objects: 4, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (4/4), 351 bytes | 0 bytes/s, done.
Total 4 (delta 3), reused 0 (delta 0)
