gtk_text_iter_starts_sentence prob

[Martin Muellenberg <MartinMue gmx net>]

hi @all

I have the following problem:

GtkTextIter pos_zuvor;

gtk_text_buffer_get_end_iter(gtktextbuffer, &pos_zuvor);

if(gtk_text_iter_starts_sentence(&pos_zuvor) == TRUE)
{
    puts("JUHU");
    textwords[i].spelling[0] = toupper(textwords[i].spelling[0]);
}

I 've never seen the funny JUHU :-( My sentence is ending with a '.'
character.
I have tested it with if(gtk_text_iter_starts_line(&pos_zuvor) == TRUE) and
it 
worked perfectly (to my confusion), after eache ENTER I saw JUHU. But I want

to know whether a new sentence is starting.

any ideas
thanks all marmll
