After having installed KDE 4.4.1, I have found a problem in using startx. I get the error bash: [: =: unary operator expected and the desktop environment is not loaded. The problem is inside /etc/X11/xinit/xinitrc.d/11-xdg-menu-KDE-4 because the variable $DESKTOP_SESSION is not defined. A simple patch is attached.
Created attachment 222523 [details, diff] 11-xdg-menu-KDE-4.patch
Fixed in 4.4.1-r2. Thanks for reporting.
