starting with just one frame:

M-x eval (setq x-no-window-manager t)

created new frame with C-x 5 2, switch to the original frame, C-x 5 0 to
kill it, set focus to firefox, switch desktops, same thing.

Sorry, what this means? (if you mean a bug on my configuration or KDE, I
concur.)

But going back to the basics, emacs -Q does not show the problem, so
after resorting to good ol' bisecting of .emacs.el, the problem is
triggered by the presence of this line:

(setq frame-title-format (concat "Emacs: %b %+%+ %f @ " (system-name)))

See my reply to Björn for more details.
