Bug#518791: PC not bootable after update of grub 1.96

[Debian]

Package: grub-common
Version: 1.96
Severity: grave

*** Please type your report below this line ***

I updated the sourced.list from "lenny" to "stable" because the package-lists for
lenny seems not to be complete any more after moving it to stable.
After that i did apt-get update und upgrade.

There where many packages installed (see attachment) also grub!
