Expected results:
no such error

Additional info:
I have kobo-client-0.4.0-1.fc19.noarch installed and it does not provide the file, seems it got removed since kobo-client-0.3.8-1.fc19.noarch ... I'm no Python expert, seems more like a kobo problem to me, but it is bkr which fails for me, so reporting for Beaker, feel free to reassign ...
