Say I am keeping ten builds of a project active. Right now #70 is done and #71
is building. If I go to

http://HOST/job/PRJ/60/

there is a "Previous Build" link pointing to

http://HOST/job/PRJ/59/

But if I click on it I get

---%<---
HTTP Status 404 -

type Status report

message

description The requested resource () is not available.
Apache Tomcat/5.5.17

Hudson should not link to a nonexistent page.
