RE: [gtkmm] TreeView Model, SEGV on append

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

Murray,
	Yes, I've done that.  

	A simple little program that uses the class that I've been
describing in a simple window with a button.  

	When the button is clicked, the signal fires a method on the window
class that calls the same 'append' method on the class as the other
application.  Just that in the test program it does not crash.  It goes on
and merrily adds as many lines as you click on the button.

	Here is the backtrace:
