Actually you added that tab. It's where you indented it having wrapped it in an "if (dlg)"

It's worth telling you now whilst it's only one tab, as it implies you should check your editor settings before writing much more code that needs to follow KDE standards where it would be a lot harder to change.

Even if it wasn't your code, it's worth pointing out existing mistakes even if we don't make them block the patch just so that they're pointed out and someone can remember to fix them.

You're acting like we're telling you off. That's really not the case, you've done a really excellent job in sorting out a very important task, we're just trying to make it even better.

Since nested event loops are potential sources of inadvertent crashes, this patch attempts to prevent that by changing how dialogs are created in kdelibs. All blocking dialog calls, i.e. those that invoke QDialog.exec(), are wrapped with QPointer and the QPointer is checked once QDialog.exec returns. See http://www.kdedevelopers.org/node/3919 for more details.
