Crash also reproducible under X11. Can confirm. When I change a setting and then leave it without saving, choosing "Discard" at the prompt makes it crash. System Settings calls "load()" when you do so and this will cause it to reload settings, updating QML stuff and eventually crashing in needsSave() because it's already being torn down. I just tried to find the exact cause for it but haven't succeeded so far. It doesn't seem to be the Qt.callLater, though. no crash no Arch Linux running plasma 5.13. *** Bug 396105 has been marked as a duplicate of this bug. *** *** Bug 396489 has been marked as a duplicate of this bug. *** *** Bug 397324 has been marked as a duplicate of this bug. *** This is also happening on Solus with Plasma 5.14.2. Clicking on the OK button makes the module crash, even when it's open "alone" (not via Settings). *** Bug 400472 has been marked as a duplicate of this bug. *** *** This bug has been marked as a duplicate of bug 397894 *** |
