prevu-init on Breezy goes wrong

Binary package hint: prevu

Hi,
I installed prevu_0.4.1-0ubuntu1_all.deb on breezy and installed the pbuilder by apt-get install.
The prevu-init call goes wrong, as it tries always to load packages from:
http://ftp.jp.debian.org/debian/dists/breezy/Release

I even called pbuilder by hand (I looked at the script steps of prevu-init) - but this still does get from some deep secret places this path. This system was never a debian install, so that I really have no idea, where the path http://ftp.jp.debian.org/debian/dists is originating.

Calling pbuilder with debugging:
//......
Building the build environment
+ mkdir -p /var/cache/prevu/builds/828
+ '[' '!' -d /var/cache/prevu/builds/828 ']'
+ echo ignoring trap cleanbuildplace exit
ignoring trap cleanbuildplace exit
+ echo ' -> running debootstrap'
 -> running debootstrap
+ DEBOOTSTRAPSCRIPT=
+ '[' -n '' ']'
+ cd /var/cache/prevu/builds/828
+ debootstrap breezy . http://ftp.jp.debian.org/debian ''
I: Retrieving Release
E: Failed getting release file http://ftp.jp.debian.org/debian/dists/breezy/Release
+ echo 'pbuilder: debootstrap failed'
pbuilder: debootstrap failed
+ exit 1

How can I avoid the wrong URL?

Thanks,
Achim
