It looks like QTimeLine::stop() gets called after KCollapsibleGroupBox is deleted. This causes QTimeLine::stateChanged to get emitted which then calls KCollapsibleGroupBox::updateChildrenVisibility() that causes the crash.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">To see the crash, clone the newAddDialog branch of Ark and run the autotests.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This diff calls QTimeLine::stop() in the KCollapsibleGroupBox dtor if it is running, before deleting the d pointer.</p></pre>
