OK, then that's a good reason for a bugfix indeed, even SIC. > One can argue that my change breaks SIC and I won't deny it.

Yes, but after the next kdevplatform release, then, to avoid breaking compilation of released code. Is the kdevplatform bugfix getting into the final 16.12 release? If I read https://community.kde.org/Schedules/Applications/16.12_Release_Schedule correctly, there's still time to sneak it in if needed, before Dec 15. Then we can re-apply the kconfig patch for KF 5.30 (January). > I leave the decision to you. At this point it's actually a decision for the kconfig maintainer, Matthew Dawson. My job is to ensure the KF5 releases are SC/BC, which in this case can be reduced to "a SIC bugfix is acceptable if we leave time for kdevplatform to get a new release which won't be hit by this". -- David Faure, fa...@kde.org, http://www.davidfaure.fr Working on KDE Frameworks 5
