Version: 1.3 (using 4.1.80 (KDE 4.1.80 (KDE 4.2 Beta1)), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.26-gentoo-r1 Steps to reproduce: 1) Goto some (IMAP) folder 2) Goto Settings->Configure KMail->Appearance->Layout 3) Switch the message preview pane layout (e.g. from the middle one to the third one) 4) Notice that the message list as well as the message preview pane are completely empty now. In order to "repopulate" them again, you have to click on some folder. I think they should be automatically "repopulated" with the contents of the currently selected folder after changing the view.
