[gtkada] Segfault in Pack_End

[Manuel Op de Coul]

I wonder if people have seen this problem too, or know if it's
GtkAda related or not.

Every dialog in my application which uses Pack_End to put a
button in a hbox crashes when opened.
This happens in recent Linux versions like Ubuntu Hoary and
Redhat Fedora 2 with gcc 3.3-5, glib 2.6.4.

Thanks,

Manuel
