Bug#255332: kde: hangs when switching windows with alt+tab

[Giuseppe D'Angelo <dangelo@cli.di.unipi.it>]

Package: kde
Version: 4:3.1.2
Severity: normal

When I move between windows using alt + tab kde hangs:
the box with the list of open windows does not disappear,
I cannot select a new window (it respondes, but doesn't work),
and I must login on a tty and kill something to get things working.
