It looks like something is definitely wrong in the managed list

Well, it seems that the problem is ManagedListGroup's itemList member
which is a QPtrList. Switching it to an stl list brings me to
stability. Everything added to the list gets destroyed OK so I guess
it's not cleaning up after itself internally. It feels odd that both
leaks I've uncovered are in the framework, I mean, sending data to an
output stream and creating and destroying lists are pretty common
operations. You'd think if there was a problem it would have appeared
elsewhere. Especially since QPtrList is used all over myth. It's
possible that the problem is with
QPtrList is not exactly the same as std list.. Its not meant to clean
up after itself, you can call the QPtrList object with
"setAutoDelete(true)" to make it behave that way though... When that
is called, the object will free up all the pointers inside on delete.
Inb this case an STL list would work, because all the items in the list
are deleted by their parent not the container.
