Re: segfault when reattaching a tree model to a tree view

Thanks for looking into it Jacques. The code sample you provided
segfaults before any window displays on both my machines. I've
attached the output to the terminal.

One more update: when I put the tree_view in a scrolled_window the
"wrong" way, where the column headers scroll away like everything
else, the problem also goes away. I do this by adding the tree_view to
the scrolled_window using scroller#add_with_viewport instead of
scroller#add.
