No biggie. You missed out a step. You have to pack the CellRenderer into
the TreeViewColumn. Add something like

	  col0.packStart(render0, true)

evidently before you call the TreeView's appendColumn().

[I was actually under the impression that you had to call it before you
call the TreeViewColumn's addAttributeMapping(). Do let me know if
that's the case]

Errors like that bubbling out of GTK are usually because you're using it
improperly. Over time, I hope we can catch this sort of thing at the
Java layer before passing down through JNI to the C GTK library. For
now, we should certainly update the javadoc a bit!
