Version: 1.9.6 (enterprise 0.20070907.709405) (using KDE 3.5.8, Kubuntu (gutsy) 4:3.5.8-0ubuntu3.1) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.22-14-generic "Go to the next/previous unread message" does not work if Threaded Message List is default to closed. How to repeat: Go to Configure Kmail -> Appearance -> Message List -> and set "Threaded Message List Options" to "Threaded default to closed". Then if you'll get new messages into "Threaded Message List" you'll be unable to read them with "Go to the next/previous unread message" command.
