Hi Janek,
hard to say, it could be many things. Did you do any sw update to the machine recently (for example kernel)?
The machine 1 issue sounds like kicker is frozen. You can try going to console and run
ps aux |grep kicker
and see what happen. You could also try to kill kicker and launch it again.
Same goes for kdesktop

For machine 2 I would suggest trying to create a new account and see if the problem happens there as well. If not,
maybe some files in your home folder got corrupted/inconsistent.

Also ~/.xsession-error may give a clue.

Cheers
  Michele
