Someone (maybe me) should probably write this down somewhere, and I'll
apologize for having not done so myself, but here's an easy way to get
a shell inside your chroot after a build failure:

session=$(schroot -bc natty-amd64)
schroot -rc $session -u root -- apt-get install -y aptitude pbuilder
schroot -rc $session -u root -- /usr/lib/pbuilder/pbuilder-satisfydepends
schroot -rc $session -- dpkg-buildpackage -b
schroot -rc $session # spawns a shell inside the chroot

then be sure to run
schroot -ec $session
when you're done.
