Bug#645092: grub-pc: postinst fails with exit status 128

[Cord Beermann]

Package: grub-pc
Version: 1.98+20100804-14+squeeze1
Severity: normal
Tags: squeeze

After Upgrade from 1.98+20100804-14 the following happens:

# dpkg --configure --pending
Setting up grub-pc (1.98+20100804-14+squeeze1) ...
dpkg: error processing grub-pc (--configure):
 subprocess installed post-installation script returned error exit status 128
Errors were encountered while processing:
 grub-pc
#

A downgrade to 1.98+20100804-14 doens't help. same error appears.

Please note that i have two machines with at least differing exit status.
Because of that i file two bugreports.
