If i created a view page I only see the breadcrumb 'home', with 'Append page title' enabled.
But when i created a custom breadcrumb for the view i get the page title twice.
Home - View title - view title.
What is kinda normal because i give it the title as breadcrumb and it just appends the page title.
So it seems the bug is in the fact it doesn't append the page title on a views page.
