Bug#545460: segfault during update of grub-pc package

[Robert Ramiega]

Package: grub-pc
Version: 1.97~beta2-2
Severity: important


While attempting to upgrade grub-pc using aptitude I got:

Setting up grub-pc (1.97~beta2-2) ...
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)   /dev/hda
Generating grub.cfg ...
Segmentation fault
dpkg: error processing grub-pc (--configure):
 subprocess installed post-installation script returned error exit status 139

This is clean install of Debian/SID done a couple of weeks ago with grub-pc chosen as
default bootloader.
