Are you sure you don't have an old version of grub-common or something from grub in /usr/local? This problem was noticed before and fixed in 1.98
----------------------------

The problem is/was with incorrect info on /boot/grub/device.map (automatically included in bug report).
The real /boot/grub/device.map was not

> *********************** END /boot/grub/device.map

But 
(hd0)	/dev/sda
(hd1)	/dev/sdb

And the disks themselves are:
fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x339be235

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         122      979933+  82  Linux swap / Solaris
/dev/sda2   *         123        1338     9767520   83  Linux

Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00028d88

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        1216     9767488+  fd  Linux raid autodetect
/dev/sdb2            1217        2432     9767520   fd  Linux raid autodetect
/dev/sdb3            2433        2918     3903795   fd  Linux raid autodetect


I was playing with boot device priority (two disks with different configurations, disk sda was a backup settings, sdb was a testing configuration for software raid. After everyting ironed out I was gonna make those disks as software mirrors. 

Now before this upgrade everything worked. After this it stopped. And update-grub only finished when I removed "(hd0)	/dev/sda" line from device.map.
