Problems after upgrade to 1.4.2

I have been running Current snapshot 20021011 fine for some time.  I've 
finally gotten around to building a new server, and installing 1.4.2 on 
it.  The install went fine, but now I am getting this on all my 7.3 clients:

Error communicating with server.  The message was:
SSL_connect error

and this on all my 8.0 clients:

There was an SSL error: [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 
'certificate verify failed')]

Here is the apache error log entry:

[Sat Feb  1 00:03:13 2003] [error] mod_ssl: SSL handshake failed (server 
woogie.
net:443, client 192.168.1.2) (OpenSSL library error follows)
[Sat Feb  1 00:03:13 2003] [error] OpenSSL: 
error:14094418:lib(20):func(148):rea
son(1048)

I have double checked that the certificate on the client matches the 
certificate on the server, and I know that the times are in sync, since 
I get the error even if I run up2date on the current server.  I even 
tried recreating the certificate, even though there was no sign that 
there was anything wrong with it since I can connect to the server fine 
with mozilla or any other browser I try.

It sounds a lot like Christian's problem except my clients are all 7.3 
or 8.0, and they all have the problem.

Anything else I need to check?

Thanks
Mike
