### Is the issue reproducible?

Yes.
#### List steps to reproduce below:

3. test ban node list right-click functionality on Menu->Help->Debug pop-up window, Peers tab.

DeleteNode(pnode);

    vNodes.clear();
    vNodesDisconnected.clear();
    vhListenSocket.clear();
    delete semOutbound;
    semOutbound = NULL;
    if(pnodeLocalHost)
        DeleteNode(pnodeLocalHost);
    pnodeLocalHost = NULL;
}

    bool fUpdateConnectionTime = false;
    GetNodeSignals().FinalizeNode(pnode->GetId(), fUpdateConnectionTime);
    if(fUpdateConnectionTime)
        addrman.Connected(pnode->addr);
    delete pnode;
