I think this was caused by phonon FTBFS
Guess not, it really is due to gstreamer-1.5 introducing new/additional include dirs (where phonon-gstreamer assumed a single include dir)
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle. Changing version to '23'. (As we did not run this process for some time, it could affect also pre-Fedora 23 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
fixed awhile back
