[gtkmm] TreeView Model, SEGV on append

["Ohrnberger, Erik" <erik_ohrnberger dme net>]

I'm hoping that someone can give me a pointer on tracking the issue down
with my code.

I build a scrolled windows, attach a treeview to it, create the
ListStore::create to create the model, and set this model to the treeview.

Next, I append my columns to the treeview and try and perform an append on
the model.  It's right on the statement below:

	TreeModel::Row row = *( pMoldListModel->append() );

Where the program gets a segv and crashes the program inside of the
gtkmm-2.2.5.  As it's crashing right inside this call into the libraries,
what do you think is went wrong?  What should I do to track this further
down?

Thanks,
	Erik.
