Can build, but won't run.

I can build my COMPO app against Gtkd3

It uses a Tree view, and it segfaults as soon as I try to select the single object that is present in the view at startup. To be honest I have never understood the GTK documentation for this stuff, but it worked fine with 2.4.

I derive a class from TreeModel, and override the methods specified by the interface.

You seem to also define a TreeModel implementation in the library, using mixins somehow. Should I be using that implementation? Do you have a working tree view example?

The stack trace to the segfault as generated by CodeBlocks 10.05 is as follows (how do I send a file). All of the action seems to happen in libgtk-3.so.
