GtkTreeView Size Issue

[Carlos Pereira <jose carlos pereira ist utl pt>]

Hi,
The working code below shows a two-column list, where the second
title, "Pages", is partially overwritten by the scrolled window:

http://www.gamgi.org/treeview.png

When the scrolled window is inactive, or when gtk_widget_set_size_request
is commented out, the title "Pages" looks fine.

A simple workaround is to add three spaces to the last title,
"Pages   " instead of "Pages", but this is not elegant...

I am doing something wrong? actually this is a old issue,
GtkCList had exactly the same problem, five years ago...

According to pkg-config --modversion gtk+-2.0, I am running GTK 2.12.5

Thanks!
Carlos
