cannot create live hdd using live-build_3.0~a47-1_all.deb

hi

I've wheezy and try to create live hdd using live-build_3.0~a47-1_all.deb

# lb config --mode debian -d wheezy -b hdd -p lxde

but get the following problems:

grep: etc/xdg/menus/debian-menu.menu: No such file or directory
grep: etc/nologin: No such file or directory
grep: run/sendsigs.omit.d/rsyslog: No such file or directory

and nothing happens.
What's wrong and howto solve it?

BTW I didn't get these problems with live-build_3.0~a45-1_all.deb.
Should I downgrade live-build?

greetings
Piotr
