As I (re)discovered an hour after sending this message. I'm not used to
C code supporting inheritance, but I've really been learning as I've
read the gtk+ source code the last few days.

Actually, no. treestoretest claimed to show how to remove rows in a
GtkTreeModelSort, but it didn't actually work. I've fixed that and will
submit a patch to gtk-devel in a few minutes.

I actually came up with the the right solution last night, but every
time I tried converting the GtkTreeModelSort iter to a child_iter my
program crashed. This lead me to beleive I was doing something wrong
even though I wasn't. When I grabbed the code in CVS the problem went
away. (I'd been using the RPMS at gtk.org.) When will the next set of
RPMS be released?
