Fix for dangling object pointers in QQmlErrors
This rarely happens - only seen with Delegates - when
- an object is created during incubation
- some error occurs in this object
- the object gets deleted before the incubation run finishes
Because the errors are delivered after the incubation run finished, the
object() pointer of QQmlError is now a dangling pointer that will crash
your application if accessed.
