title: Jenkins Build job fails -revision check failed
body: <p>I'm receiving the below error from Monday. It was perfectly working fine without any issues last week. There were no changes done to the configuration. What could be the reason for this error here?</p>
  
  <p>I've googled a bit and found this: <a href="http://www.codedisqus.com/CmVjPqeUge/issues-with-jenkins-and-svn-proxy.html" rel="nofollow">http://www.codedisqus.com/CmVjPqeUge/issues-with-jenkins-and-svn-proxy.html</a> , that's the exact scenario i'm facing. Except for a fact, i don't have any proxy between slave and master machines. </p>
  
  <p>SvnKIT version: 1.5 ( but i don't think it has to do with SVN KIT version, since the latest once is 2.5 )</p>
