+Summary: TextBuffer insert method using RefPtr<TextBuffer> yields core dump on G_IS_OBJECT assertion
+
+Word Description
+----------------
+    When I create a TextBuffer and perform some insertion of text into it,
+I will eventually get a core dump due to an object integrity check by an
+assertion.  Originally, I was using the TextBuffer in conjunction with a
+TextView; however, I have narrowed down the sequence of operations that
+seem to generate this problem.  In addition, the assertion appears to be at
+the time of an "un-reference" by the RefPtr of the TextBuffer.
+    To simplify the problem I wrote a *very* simple test program and
+provide the following to assist debugging:
+
+File: t.cc
+------------------
+#include        <gtkmm.h>
+
+int     main (int argc, char** argv)
+{
+  Glib::RefPtr<Gtk::TextBuffer> rptxtbuf        = Gtk::TextBuffer::create ();
+
+  rptxtbuf->insert_at_cursor ("This line is a test.\n");
+
+  return 0;
+}
+-------------------
+In Bash shell:
+
+$ g++ t.cc -g `pkg-config gtkmm-2.0 --cflags --libs` -o t
+$ ./t
+
+(process:21719): GLib-GObject-CRITICAL **:
+gtype.c:1806:g_type_register_static(): initialization assertion failed, use
+g_type_init() prior to this function

+Such a member function does not yet exist as I have only added the

+duplicate the problem consistently.
+  In any case, I now provide the results of the modified test program

+the --g-fatal-warnings flag.  The stack trace still show the problem
+in the "un-ref" of the TextBuffer RefPtr.
