I used qtwebchannel from github repository in dev branch
Description
If an object (lets name it A) is returned by a function A is saved in wrappedObjects. But if the website reloads and A stays in memory the transports-vector of As ObjectInfo wrapper is not updated. So in this vector the deleted transport-object pointer keeps saved. Now if in A a property changes the application crashes because in QMetaObjectPublisher::sendPendingPropertyUpdates the deleted transport-objects is tried to be used.
So if a transport-object is added to wrappedObjects in QMetaObjectPublisher::wrapResults it is needed to connect the transports destroyed signal to a function which removes the transport-object from ObjectInfo::transports.
