The source of the bug is qdbus (4:4.8.4+dfsg-0ubuntu9). The binary file was moved from /usr/bin/qdbus to /usr/lib/i386-linux-gnu/qt4/bin/qdbus. So it is not in root's PATH and can't be run in powerbtn.sh:46.
There are TEMPORARY solutions for users:
1) Install http://packages.ubuntu.com/quantal/qdbus and hold it.
2) Create symlink from /usr/bin/qdbus pointing to /usr/lib/i386-linux-gnu/qt4/bin/qdbus.
3) Patch /etc/acpi/powerbtn.sh:
diff --git a/acpi/powerbtn.sh b/acpi/powerbtn.sh

I don't know whom to ask to fix this bug. So please tell the right
person to fix it, because it's a release blocking bug I think.
