Monitoring an external job (described at http://wiki.jenkins-ci.org/display/JENKINS/Monitoring+external+jobs) doesn't work if the Hudson instance has CSRF protection enabled, because the cli doesn't retrieve a crumb before attempting to submit the result. An example solution is described in one of the blue boxes at <http://wiki.jenkins-ci.org/display/JENKINS/Subversion+Plugin>. I'll attach a patch that uses this trick to fix the problem.
