Which version of Subversion are you running with? Do you have the latest revisions, to use the latest repair tools? And can you do an export of the current contents, set aside the old repository, and switch people to the new repo with the necessary tags, but without the corrupted history? This is an approach I've used successfully for people migrating among source control systems or cleaning up projects where inappropriae data was in the primary repository. (Spurious DVD images and files with passwords were particularly common problems.)
