Bug#433675: apt-setup: use_mirror variable doesn't work properly

[Alexis Bezverkhyy <bezvezky@gmail.com>]

Package: apt-setup
Severity: important

Debian Installation manual says that "d-i apt-setup/use_mirror boolean
false" will setup apt without network mirror. This setting doesn't work.
Debian installer still asks for a mirror. In fact use_mirror is not
boolean, because "d-i apt-setup/use_mirror string false" works.

I think the
problem is in '50mirror' file near :
"db_get apt-setup/use_mirror
if [ "$RET" = false ]; then
    exit 1
fi" or in some template.
