Ktextaddons renamed those libs, no longer KF5 .so but KPim5, pimcommon and kjots were rebuild for that change, but it is known that kmail also links directly to ktextaddons, not clear through what package, so ktextaddons update will have to wait until a full rebuild of KDE Apps.
This is a [build] repo issue only, regular users are not effected. Fix by getting the updated back from the apps repo. Cleaning with akonadictl will probably be needed.
Issue is fixed in the build repo by rebuilding more of the kdepim stack.
