 IMO the user should do that. For the reasons Thiago mentioned, and also for 
the reason that you simply can't do it otherwise. The control flow has to 
return normally, otherwise the applications ends up with the broken state that 
this KAutoPointer proposal tries to patch over with even more breakage.

 Since Qt is going to get a scoped pointer, the simplest and best option seems 
to be waiting for that, including a copy of it with code that wants to use it 
now (it's all inline anyway), and, independently, the Qt bug leading to the 
crashes with the dialogs should be fixed.
