My fixes for https://bugreports.qt.io/browse/QTBUG-67559 have recently introduced a crash in KDE:


Quoting the commit message from my patch that reverts  https://codereview.qt-project.org/#/c/245480/:

"Revert all Menu delegate patches

This reverts the following commits:

The fix for QTBUG-67559 has caused lots of issues, with the latest being a
crash right before the 5.12 release. The bug that they fix is a P2,
so it's not worth the hassle. The patches might be able to be resubmitted
to dev after the crash is fixed.

Change-Id: Ic192c7a302176bcdb2503b636b3462b10898a2ba
Fixes: QTBUG-71770"

I believe that the patches are correct in principle, and the crash is probably just an oversight and not a fundamental problem, but I don't want to hold up the release for a P2 that has already required lots of follow-up fixes.

"Ok, but then we should agree if QTBUG-71770 is a blocker or can we release Qt 5.12.0 with it as known issue. It is a crash but if you can't reproduce the issue it sounds like a corner case for me and so on we should be able to keep it as known issue to minimize new risks."

So I thought I'd check here since I haven't gotten any response elsewhere when asking about what to do.
