The patch might be too aggressive in removing existing history items and we could do something more specific, like removing/updating only when the url change triggers the error.

HistoryItem* child = parentHistoryItem->childItemWithTarget(m_frame.tree().uniqueName());
if (child && child->url() != error.failingURL())
    parentHistoryItem->removeChildItem(child);
