Created attachment 1017028 [details] suggested patch EPEL apparently has only Server variant of RHEL-7, so we don't have gtkhtml3 there. I am not sure whether you like the unified SPEC file for all branches.
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
