bug with sardu and gparted

I beg your pardon for my bad english

After used sardu ( 2.0.0 beta 5b or 1.0.73 e) to make a iso, i test this iso with virtualbox (or virtualpc or mobalivecd). In this iso i have :
clonezilla 1.2.6-38
gparted-live-0.7.0-2 (or 0.6.4-1 but the problem is always the same)
ubcd50rc2
xpud-0.9.2
redobackup-livecd-0.9.7

When i run virtualbox with the sardu.iso, after the sardu's menu, i choose clonezilla or ubcdor xpud or redobackup, and all of these applications run correctly. But if i choose gparted, gparted load and i obtain this :
........
updating /etc/gparted-live/gparted-live.conf based on kernel parameters it found... done!
No accountwith NOPASSWD sudo privilege was found!
Program terminated!
startpar : service(s) returned failure : start-gparted-live ... failed!
Runnig script in rc2.d/ took 1 second.

Debian GNU/Linux squeeze/sid localhost.localdomain tty1

localhost.localdomain login :

.........


So gparted ask me a login and after a password.

with sardu 1.0.73 c and gparted 0.6.2-2 i don't have this problem.

If i load the gparted.iso in virtualbox (or virtualpc or mobalivecd), gparted load and run correctly without demand login and password.

So have you this problem? and can you help me?

Thanks a lot and excuse me again for my bad english

Thanks for feedback
Resolved
the 9-11 i release the final version of SARDU 2 with this fix
The error is only of gparted, the string of boot was obsolete , now i make a rules for autoupdate based on the string of iso
