aptitude works as root, not with sudo

Hi.

As the subject says, I've tried aptitude as root (runs perfectly),
and with sudo. When I use sudo, I can't update the package database:

sudo aptitude update

But I can use sudo dselect, sudo apt-get, etc, without problems. (And
/usr/bin/aptitude is close to /use/bin/apt-get in /etc/sudoers, both
should work the same)

Could someone please try to reproduce this? Is there something I missed,
maybe?

Thanks,
J.
