Created attachment 589166 [details, diff] Fix qtwebengine-5.12.3 build with recent linux kernel.
Dupe of bug #692352 I suppose?
Yes, indeed. I was looking for open bug reports only. Nevertheless, qtwebengine-5.12.4 is still marked as amd64 unstable and since harfbuzz-2.6.1 was marked amd64 stable yesterday, this triggered recompilation of qtwebengine-5.12.3.
