Comment 9 for bug 746892

I second the upgrading to Critical importance, because this bug is indistinguishable from a "I have to hard-reboot my computer now" bug, even to advanced users (though, advanced users may attempt a logout with only mouse+clicks, or ctrl[wait 2 sec]+alt[wait 2 sec]+f1[wait 2 sec], then sudo /etc/init.d/kdm restart or the new equivalent command), and the cause is not traceable or understandable even to advanced users.
