Thanks for your hints. Yes, the code was incomplete. But I think the
attached code should work. It still returns:

(<unknown>:20960): Gtk-CRITICAL **: gtk_tree_path_to_string: assertion
`path != NULL' failed
path=(null)

Am I still doing something wrong?

The problem I'm trying to reproduce is the testcase from
http://git.gnome.org/cgit/perl-Gtk2/tree/t/GtkTreeView.t. This one fails
in line 233 (->to_string()) on recent Debian system, because it seems
the path returned is NULL. So I'm trying to program this in C to check,
if the result is the same. And it seems to be the case.

Regards, Daniel
