The rep_cache.db is just an sqlite database which makes checksums to
representation ids so that they can be reused by the storage system.
It can safely be deleted, with the consequence that redundant data may
be stored in the system. I don't know why it would be causing
problems, except for the fact that some open Subversion fs connection
might be holding a handle to it.
