    I'm really no treeview grokker, but I came across some similar
behaviour; I was using a pixbuf cell renderer and in some cases I
couldn't find the appropriate pixbuf resource, in this case I found
that the cell renderer would default to a pixbuf found in the same
column but from a different row, but only when I would mouse over it.

If you are experiencing some obscure bug in GTK+, the above info might
help you fix it :)

In any case, I really doubt that this has anything to do with
using threads.

A naive guess of mine would be to suggest you try putting
gtk_widget_queue_draw (treeview) in your timeout function after
treeview manipulation (ofcourse it doesn't really make sence
that you would have to).
