Rudder

If in rudder-web.properties, the Rudder Technique Reference Library branch is not the same than the /var/rudder/configuration-repository branch, after a migration from 2.3 to 2.4.0~beta3, Rudder is broken.

in rudder-web.properties:

rudder.ptlib.git.refs.path=refs/heads/master

in /var/rudder/configuration-repository :

root@server:/var/rudder/configuration-repository# git branch
* brokenbranch
  master

Rudder can't start with this error message:

Even if I try to reapply rudder-upgrade script to the good branch, Rudder still can't be started with the same error message.
