what the heck is that??? Now this refreshes some old memories.... Can you please try to
1) reboot, then run that again and see if you still get this weirdo error about /root/.kde4/tmp-K7-2400
2) if so, or even if not, then please edit /usr/bin/lomanager and exchange the lines 123 and 124, save the file and run lomanager again, let's see what that does.
please let me know what happens,
