Also I have that error:

Gtk-WARNING **: Invalid text buffer iterator: either the iterator 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 across 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
