Tests from python-nose fail when run with python-3.5. Failures were already reported to upstream https://github.com/nose-devs/nose/issues/928 As this seems to affect only output from nose and nose is used by other packages to run their tests I temporarily switched off tests for python3 build of the package so I can continue with python-3.5 rebuild. If you wish to investigate this you can find python-3.5 in tag f24-python3.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
