Your package python-nose failed to build from source in current rawhide. http://koji.fedoraproject.org/koji/taskinfo?taskID=5759030 For details on mass rebuild see https://fedoraproject.org/wiki/Fedora_20_Mass_Rebuild
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle. Changing version to '20'. More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora20
Has this been fixed? Thanks.
There are concurrency tests that rely on certain things happening in less than a second, which sometimes fails on slower builders. I just successfully built nose in rawhide: http://koji.fedoraproject.org/koji/taskinfo?taskID=6085514
