Bug in GtkText

[Nuno Ferreira <nmrf rnl ist utl pt>]

I think I found a bug in GtkText. When starting gnomecal it never shows up
and eats all your cpu IF you have an event on the current day.
I found out it's spinning in this loop at line 3389

- gtktext.c::find_line_containing_point 
/* Scroll the bottom of the line is on screen, or until
 * the line is the first onscreen line.
 */
while (cache->next != text->line_start_cache && lph > height)
{
    TEXT_SHOW_LINE (text, cache, "cache");
    TEXT_SHOW_LINE (text, cache->next, "cache->next");
    scroll_int (text, LINE_HEIGHT(CACHE_DATA(cache->next)));
    lph = pixel_height_of (text, cache->next);
}

As you can see cache->next never changes so the loop can never finish.
