To reproduce:
1-install only IceWM and KDE3 as WM/DE on TW or Leap
2-open a KDE3 session from KDM3
3-attach a USB stick or USB HD or insert OM
4-select open in new window when popup window asks what to do

Actual behavior:
1-new window opens

Expected behavior:
1-new window opens
2-as happens in Plasma 5, something appears in the systemtray to indicate
removable media is attached and which facilitates eventual OM ejection or safe
USB device removal

Notes:
1-this applies on at least 7 different TW, 42.1 & 42.2 installations across 5
hosts (big31, big41, gx62b, hpg33, k8mmv; I have more yet to try).
2-it does not apply on one host (easystreet) that is not mine and that I no
longer possess, on which I upgraded to 42.2 from 13.1, and on which
solver.onlyRequires = true in zypp.conf is not present, as is the case with all
my own installations.
