I know it's been a week but no-one else has offered any input.

It's not explicitly specified but I presume /usr/home is a directory
within /usr. (Not a symlink or mountpoint).
What version were you running before 10-current?
Is /usr UFS2 with softupdates+journalling?
Is userland (specifically /sbin/dump and fsck) aligned with the kernel?
Any idea what SVN revision your system corresponds to?
Have there been any unclean shutdowns of the system?
"Tape blocks" reported by dump(8) are (as far as I can tell) always
1KB. Your df(1) output reports 111GB used in /usr but dump(8) only
shows ~57GB being backed up. Do you have any idea why there's such a
difference? How much space would you expect to be used in /usr?
Do you have the fsck(8) output? If so, how much space does it report?
Have you checked the dumps for all the other filesystems? Are any of
them missing data or containing unexpectedly empty directories?
I don't suppose you have the output from hd(1), stat(1) and "ls -al"
of /usr & /usr/home?
