The gtk_text_buffer_get_text() routine does *not* work.

No it's not. that url doesn't resolve (at least as far as the #id tag
goes).  Additionally, your suggestion doesn't work either...

In both of these instances I get the following error:

 Gtk-WARNING **: Invalid text buffer iterator: either the iter
ator is uninitialized, or the characters/pixbufs/widgets in the buffer have been
 modified since the iterator was created.
You must use marks, character numbers, or line numbers to preserve a position ac
ross buffer modifications.
You can apply tags and insert marks without invalidating your iterators,
but any mutation that affects 'indexable' buffer contents (contents that can be
referred to by character offset)
will invalidate all outstanding iterators
