Re-using Gtk2_ExceptionDump
You can make use of the brain power that went into
the development of Gtk2_ExceptionDump
by embedding the stack trace treeview into your own application.
There class you want is
Gtk2_ExceptionDump_Stack.
It's a subclass of GtkTreeView and should be
embedded in a GtkScrolledWindow if you use it.
The constructor takes the exception object, but it
can be omitted and set later by using setException().
