I am a huge fan of drover, but discovered this morning that it wasn't working with my svn client, even though it was version 1.6.15.  I did some poking around, and found that because SlikSvn doesn't give a revision number in its --version information dump, it was failing to match the regex in drover.py.  I then noticed that the revision number wasn't being used for anything, so I removed it and everything worked great again.
