Bug#453334: general: apt and aptitude stop work

[Rafael <EagleScreen@gmail.com>]

Package: general
Severity: important

apt-get or aptitude stop work when i uninstall a linux image and /boot/grub/menu.lst was deleted.
Installer should create automatically a new menu.lst file, but when it's time to do it, process stop.
watch the console output:
