The linux-i586 builds are failing frequently on Mach 5 with this error:

Prebuilds always start with a clean workspace and pull a fresh set of repositories and builds always start with a clean workspace before fetching source bundles, ie., there is not workspace pollution coming from the jenkins builds themselves.
