I haven't seen this, but my first instinct tells me that this is not
related to svn. Seems to me to be purely an apache/openssl/certificate
issue. Maybe there is something strange about your client certs, and
openssl 0.9.8k handles them differently from 0.9.8g?

Can you try some tests without svn, for instance set up apache to
serve a simple static page protected by client cert authentication,
and try to access that with that cert using openssl 0.9.8g vs. 0.9.8k?
Or try to build an svn client on your new machine with openssl 0.9.8g
instead of k?

Disclaimer: I have never tried svn with client cert authentication, so
I'm just guessing here based on your account of the facts ...

Cheers,
