On that NOTIFY comment, you can add CONSTANT instead to your property declarations if they are indeed read only. Also, why are you checking your private member variables for NULL? They are not pointers. Why a QLIst<QObject*> instead of a QList<KeyValueListItem*>? Why it segfaults? Who knows, not enough details, why don't you run it through gdb and get a backtrace?

using QLIst<QObject*> because QList<KeyValueListItem*> gives an error which its not registered with the qt meta system
I've got around the problem though by using QVariant::fromValue(xxxx) like in the examples.

conditions->append(new KeyValueListItem("New other (see details)", ItemFilterType_CONDITION, "1500", false));
