The xdg-desktop-portel-kde crash is bug 458865 and completely unrelated to the freezes.

Ok, I see. Could you then please close this bug?

Just wanted to add that the desktop freezes seem to strongly correlate with xdg-desktop-portel-kde crashes. Just observed this another time.

The xdg-desktop-portal-kde crashes happen *after* a reboot. That's why they correlate.
