This is indeed an issue with qListForm when Form type is set to NewListItem. qListForm performs a couple of actions after the new item is created (triggers create event). Some of the actions following the initial save will try to update dependent list item (trigger other dependent list items), or update Rich Text field (because user may add attachment to the field and list item ID will be needed after item is created) and etc. Quest will be looking into handling Rich Text update better in order to avoid this common issue.
