Bug#452167: ALT TAB now locks system! Must reboot

[jidanni@jidanni.org]

Mouse still moves... sounds like my problem:

Holy moly, now "Hold down ALT, press TAB" locks the whole system.
Even the linux-doc-2.6.*/Documentation/sysrq.txt.gz keys can't break
out of it very well often.

At the the time I was in
-xdm
   `-sh /home/jidanni/.xsession
       |-icewm-session
       |   |-icewm
       |   |-icewmbg
       |   `-icewmtray
And ALT TAB TAB... is normally how I switch around icewm windows, and
there have been no new versions of icewm, but there have for X windows.
