Shared-mime-info 1.9 doesn't show RAR mime type in the .rar archives icons. With version 1.6.2 there is RAR sign in the icon. None of the latest versions after 1.6.2 doesn't show the rar sigh in the archive icon. With shared-mime-info 1.9 there is nothing, but blank space. I already filed the bug in 2016-11-14 but it was never fixed despite the "Fixed" status. https://bugs.kde.org/show_bug.cgi?id=372461
