<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Just looked at kdelibs4 code: the bug cannot happen there because finished() is always emitted after okClicked(). (in kdelibs4 all of those were handled by KDialog)</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When one closes KCMultiDialog with OK, QDialog::finished() can be emitted before the clicked() signal of the OK button. This causes the following sequence to happen:
- KCMultiDialogPrivate::_k_dialogClosed
* deletes the KCModule
- KCModuleProxyPrivate::_k_moduleDestroyed
* sets kcm to 0
- KCMultiDialog::slotOkClicked
- KCMultiDialogPrivate::apply
- KCModuleProxy::save
- KCModuleProxyPrivate::realModule
* notices kcm is 0, so recreates it
* calls kcm->save()
- KWinDesktopConfig::save()
* crashes because it expects kcm->load() to have been called
To avoid this, trigger the cleanup code in closeEvent() rather than when finished() is emitted, as we can be sure closeEvent() is always called *after* the methods connected to the button box signals has executed.
