I had similar problems after v1.4.3 => v1.4.5 upgrade.
Sometimes md-sums where identical between same files
(I replaced them manually to zeros.) and sometimes letters
in path names had changed. Also revisions years ago became
suddently corrupted and no one could "svn update" anymore.

I had to fix them by editing revision records manually
with VI -editor. I also used python script to analyse problems
and had to add extra printf -clauses to Subversion C-source files
in order to locate errors.

I have upgraded the server to v1.4.6 and "svnadmin verify" has not
reported any problems since then. I am using FSFS.
