When I try to use the UI to compare two job configuration histories an error is thrown which indicates a path to a job which truly does not exist.

39636 java.lang.IllegalArgumentException: Unable to get history from: E:\Jenkins\config-history\jobs/SND-Admin-WSA/2013-10-23_15-47-43

The path should be
E:/Jenkins/config-history/jobs/WIA_Deploy/jobs/SND-Admin-WSA/2013-10-23_15-47-43
