"Show bookmark toolbar" is an option which may be
found in the "Settings" menu of Konqueror. It is
not enabled by default.
If you enable it, it doesn't work. A "toolbar"
perhaps 2 pixels tall sort of appears. Not so
useful. It remains only 2 pixels tall if you go
into Bookmarks->Edit Bookmarks, and create some
bookmarks then use "Settings->Set as bookmark
Works in 2.2-0.alpha2.1
