Possibly due to rep-sharing?  Does db/revs/0/192 contain the number
"162" in ASCII decimal delimited by whitespace?  You can check that with
the following command:   grep -a "^text:" db/revs/0/192

Does 'svnadmin dump -r 162 >NUL' work ?

To answer your question: yes, most definitely a copy of the r192 (and/or
r162) rev file would allow to pinpoint the problem, however you might
not want to share those files on a public list as they may contain
sensitive data (versioned file contents).
