What seems to be happening is this: ClassicMode::initEvent() creates d->classicWidget, a QSplitter with no parent. KParts::PartManager::PartManager() is called for that splitter, which calls addManagedTopLevelWidget() for it. At this stage isTopLevel() for the splitter is true and so it is added to the d->m_managedTopLevelWidgets list. SettingsBase::changePlugin() adds the splitter to the stackedWidget, which takes ownership of the splitter. When systemsettings5 is closed, KParts::PartManager::removeManagedTopLevelWidget() is called by the destroyed() signal of the splitter. However, by this point isTopLevel() for the splitter is false (because it has been reparented above) and so it is not removed from d->m_managedTopLevelWidgets. KParts::PartManager::~PartManager() accesses the splitter, which has already been destroyed but still remains in d->m_managedTopLevelWidgets => crash. bug 356771 suggests that the problem is still in version 5.5.1. In this version I'm also able to reproduce it. *** Bug 356771 has been marked as a duplicate of this bug. *** Git commit 5ac5dfb28014035e3704ae8bf8076001e5955ceb by Jonathan Marten. Committed on 06/01/2016 at 17:59. Pushed by marten into branch 'master'. PartManager: stop tracking a widget even if it is no longer top level Fixes an access-to-deleted-object crash if a widget is top level when it is added but no longer top level when it is removed. Seen when exiting System Settings.
