I had a similiar problem with my application (http://lostirc.sf.net/)
and asked on several mailing list on how to solve it, but people told me
that it was "expected behaviour" with GtkTreeView, whereas GtkText was
buggy in this aspect.

As far as I remember, the workaround I found was to use:

    set_size_request(0, -1); // on the scrolledwindow

and

    set_wrap_mode(Gtk::WRAP_CHAR); // on the textview

However, wrapping on characters isn't always the prettiest solution, so
I'm quite annoyed with the behaviour you describe as well.

A quick grep through their sources tells me that they use GtkText rather
than GtkTextView.

Hope that helps,
