/dev/null: access denied

[Pavel Novák <lists@innuendo.cz>]

Hi people!
I added new sources for KDE 3.4:
deb http://pkg-kde.alioth.debian.org/kde-3.4.0/ ./

and type dist-upgrade on my Debian unstable. It downloaded all kde
packages and many more others to upgrade.

After install and reboot I can't run many programs because of bad
privileges on /dev*.

For example startkde or zsh shows error: /dev/null: access denied. When
I do hack chmod a+rw /dev/* it's relatively ok till next reboot.

Can you help me where would be problem please?
