python-cjson should be retired as the development has been discontinued (last release in 2007). Furthermore the module contains compiled C code which is prone to potential security issues (especially as the module will likely work on untrusted user input). Other json libraries in Python are faster now due to continouos improvements and switching from one library to another should be trivial. Therefore python-cjson should be retired.
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.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19
package is retired now for F20/rawhide. We'll keep it in EPEL+F18/F19 so we don't break existing setups.
