Re: Invalid TextBuffer iterator

[Yann Leydier <yann leydier info>]

Hi,

I think there is no need to create a new TextBuffer, you could just 
write (and that's what I did in an application that uses a TextView 
whithout crashing):
m_refTextBuffer = get_buffer();

Or maybe creating the Mark after linking the TextBuffer to the TextView 
would do the trick…
