I would say that this is a little obstacles promotion Qt. The problem of some deeper, some parts of Qt are not exception safe (at least in QtCore module). This prevents the using with Qt some libraries that use exceptions, so could potentially lead to memory leaks. In addition, I can't imagine a more natural and easy way to handle error occurring in the constructor, except through the exception. May be someone know?
