libparted ped_disk_get_max_partition_geometry() gives wrong size

[ben]

With libparted, version 2.3, I have been having a problem with 
ped_disk_get_max_partition_geometry(). The function returns values that are 
correct for the beginning of a partition but too small for the end. This only 
seems to happen with MS-DOS disk labels. The returned value can be short by 
over 2 megabytes and can even be *smaller* than the partition that already 
exists there.

I have seen the same behavior with disks of 40 GB too 1 TB and even flash 
drives. GParted reports the correct sizes and often shows substantial 
unallocated space after a partition that was supposed to be maximized.

I am running Debian Linux.

Thank you.
