Problem with "reorderable" treeview

[Robert Pearce <rob bdt-home demon co uk>]

I have a treeview widget showing a liststore, and some background tasks 
updating the contents. I would like to be able to mark the view 
"reorderable", but I've ended up with loads of other objects referencing 
rows of the treeview (by iterator) for the background work, and moving 
rows around breaks all those references and causes errors.

IS there a better way to reference members of a liststore, so that 
reordering the treeview won't break the references?

Or, alternatively, how can I best hook something up to the reordering 
event so that I can repair all the references?

Thanks
