[Beaver-devel] Invalid iterator bug

[Leslie P. Polzer]

I get core dump this every once in a while when I do indenting:

---

(beaver:291): Gtk-CRITICAL **: file gtktextbuffer.c: line 3458 
(gtk_text_buffer_get_selection_bounds): assertion `GTK_IS_TEXT_BUFFER (buffer)' 
failed

(beaver:291): 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
