However, that does not help and plasma-desktop takes ages to start. Looking into plasma-desktop with strace shows the following line is repeated over and over again: 16653 poll([{fd=5, events=POLLIN}], 1, 14485) = 1 ([{fd=5, revents=POLLIN}]) 16653 recvmsg(5, {msg_name(0)=NULL, msg_iov(1)=[{"l\4\1\1\0\0\0\0\241w\2\0n\0\0\0\1\1o\0\23\0\0\0/StatusNotifierItem\0\0\0\0\0\2\1s\0\32\0\0\0org.kde.StatusNotifierItem\0\0\0\0\0\0\3\1s\0\n\0\0\0NewToolTip\0\0\0\0\0\0\7\1s\0\5\0\0\0:1.37\0\0\0desktop.DBus\0\0\0\0\10\1g\0\3sss\0\0\0\0\0\0\0\0\10\0\0\0:1.75805\0\0\0\0\10\0\0\0:1.75805\0\0\0\0\0\0\0\0\0\0per\0\0\0\0\0\0\0\22\0\0\0applications-other\0\0\5\0\0\0Apper\0\0\0Y\0\0\0Distribution upgrade available<br/><b>precise 12.04 LTS</b><br/>The latest stable release\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0Steuerprogramm f\303\274r Nepomuk\0\0\0\0\0\n\0\0\0ItemIsMenu\0\1b\0\0\0\0\0\0\0\4\0\0\0Menu\0\1o\0\10\0\0\0/MenuBar\0\0\0\0\0\0\0\0\17\0\0\0OverlayIconName\0\1s\0\0\0\0\0\0\0\0\0\0\21\0\0\0OverlayIconPixmap\0\7a(iiay)\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 128 16653 recvmsg(5, 0x7fff7e8fb600, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) with the exact text changing every now and then. (Ressembling the notifications I just recevied, or just will recevie in the notification area.)
