Description of problem: Release notes shown in Lost&Found KDE menu. Version-Release number of selected component (if applicable): fedora-release-notes-20-0.0 Bug 972250 was fixed in F19, but appeared again on F20 Alpha RC2 KDE image.
To quote the f19 bug, Per the desktop-menu-spec: http://standards.freedesktop.org/menu-spec/latest/apas02.html Documentation is an Additional Category and MUST be used together with a Main Category from the list in: http://standards.freedesktop.org/menu-spec/latest/apa.html#main-category-registry (System, i.e. "Categories=System;Documentation;", is a valid option).
The desktop file has been corrected (in master, even!) - a pending update will fix this.
confirmed fixed in fedora-release-notes-20-0.9.noarch
