*** Bug 449990 has been marked as a duplicate of this bug. *** - change splash - apply - close window while applying - crash What happens is that the closing pulls the objects out from under the ::save function and so it then sends signals into the void and crashes. I'm not sure how to mitigate this, we kind of need to block in ::save because of how the KCM API works. Possibly the solution could be to manually run a nested eventloop and abort it in the destructor. Ultimately though the KCM API ought to become async. It's not the first time that having to block inside a ::save is causing trouble. I opened an MR to fix this issue. https://invent.kde.org/plasma/plymouth-kcm/-/merge_requests/18 *** Bug 475067 has been marked as a duplicate of this bug. *** Thanks for the bug report.
