I'm sorry that I have opened a new ticket, but I did not want to trigger a spam avalanche to security@gentoo.org in ticket 578780 https://bugs.gentoo.org/show_bug.cgi?id=578780 10 apr 2016, version 1.6.1, fixed unnecessary opening kwallet if the option is not configured. 10 apr 2016, version 1.6.2, removed unused toolbar from mainwindow; changed icon for application with standard plasma-breeze lock icon
Thanks, fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=352f3ac4a9c1db8173d065dc5cbba147fdadd419
