Ernestina:

you did not specify on which platform this was. However, I was able to
reproduce this on my linux machine, and we will make sure to fix the demo
before the next release of GtkAda.
However, this shouldn't be a problem for you if you want to use the Gtk_Tree
widget in your own application.

It is interesting to know that the authors of gtk+ recommand in fact to use
Gtk_Ctree, which is far more powerful and less broken. This is by the way the
only solution if you want to include pixmaps in your tree.
