It's the same for me, 5 seconds hang up, before the window appears. I use xfrun4 instead of xfce4-appfinder, but the result is very similar (Ubuntu 12.04, XFCE 4.8.0.3), strace attached.
--disable-server option didn't work (no this option for xfrun4?), but I killed the already running xfrun4 (xfrun4 --daemon) and it helped.
