That's the version that mostly seems to work (there is a bug in a method that currently iterates over the list one entry per call) but throws pages and pages of GTK warnings and "critical"s when run. In particular, when creating and populating the ListStore, and iterating over it.

This is probably due to a static instance somewhere in your code. It's
generally impossible to ensure that glibmm/gtkmm is initialized before
static instances, because the sequence of static instance initialization
is not well defined.
