This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

I haven't done really any testing, but it at least builds for me in koji (http://koji.fedoraproject.org/koji/taskinfo?taskID=7093266)

Sorry that took so long. http://koji.fedoraproject.org/koji/taskinfo?taskID=7554447 is running with your changes Matěj, local and mock builds worked very smoothly already.

Thanks & regards, Phil
