Actually, that blog is nice, but I don't really see how this is easily fixable. If we get at some point such a dbus call, we would need to ensure we check for all things on the stack to be still ok, e.g. is the view manager still there and so on. See no real value in trying to fix that, actually. Have you checked if this still works with the current code? Yes, it will still random crash thought we only use:
const QList<QUrl> urls = QFileDialog::getOpenFileUrls(m_mainWindow, i18n("Open File"), cv->document()->url());
We would need really to guard all things on the stack for the current function, here we are in a view manager member and Co.
That makes no sense for me and I rather have such crashs than uglifying all our code base for no real reason. (if users script stuff via dbus + do GUI interactions during that scripts are running, they are doomed)

=> Yeah, if that ever happens, perhaps, but for editing automation one more should write the javascripts we support.
