I've seen this problem by myself with trying to get ServerView management SSL working on my test SLES10 server. Had same errors.
And i couldn't find solution - then installed apache2 cocnfig files from old sles9 and... problem disappeard
So it is something with default ssl/vhost config in SLES10.
Now server is reinstalled with opensuse10.* perfect setup (but with SLES10 SP1) and SSL on my apache2 works without problem.
