BUG: 387854
The pre-defined searches (Documents, Videos, etc) all default to no search text. https://cgit.kde.org/dolphin.git/commit/?id=702429ac8e64a5aff4e110a56f526b96ecb795fd changed their window title from "baloosearch - /" to "Empty Search", but the search isn't really empty; it just lacks a search string. It's still looking for documents, or videos, or whatever.
