Did you hand-type this? Should look like u'Centos...' not 'uCentOS...' ...
I'll check over the repo matching code. It may be we missed a Unicode comparison.
hand type the name of the repo ? i cant really remember as this is a test system so i go through lots of changes with it.
I dont really remember doing that but i suppose it is possible, either way the repo did work pre 1.6.1 so just think somewhere something needs tweaking
