I'm getting a similar error message the original bug poster is getting. My setup is two CentOS servers, one master one slave. The slave finishes the build successfully and the archiving hangs. Jenkins version 1.4886 I believe.
This does indeed sound like it's related to JENKINS-11586.
This bug is a real pain for us since we have to figure out some way of 'archiving' the packages without using the built-in archiving tools now... Makes life much more difficult :/
