So this might fall into the category of "putting the wrong TreeModel in
the TreeView"?

If you're using a TreeModelSort to wrap a ListStore, you put the
TreeModelSort into the TreeView.

Iterating over the underlying ListStore should, however, remain fine;
changes to the sort discriminator won't affect your ability to finish
looping over the model.

[at least, I've had no problem with it; I did have a case once where the
data displayed in the TreeView would wobble a bit as I was updating all
the rows because the sorting values were not unique, and so it sometimes
flip-flopped a bit when confronted with equal values]

Anyway, if you're still stuck you'll need to show us your code (more to
the point, to boil your problem down to code that someone can
comprehend, or better yet, if it's really a bug, write a TestCase that
can go into the test suite).
