dmwm/WMCore — pull request #4298 by samircury (2012-11-23 17:24:12+00:00)
Title: Failed jobs histograms

Implements it as asked in #4215

*DO NOT* Merge it before merging #4296, reason is that this imports both patches there (cherry-pick), so there might be problems to merge this directly.

Let me know (here preferentially) if there will be amends in #4296, so I have to update and fix things on my side.
