Subversion bug: "/build/buildd/subversion-1.6.6dfsg/subversion/

Good day,

where can I report this:

Ubuntu 10.10.3 amd64:

fabio_at_nietzsche:~$ uname -a; svnserve --version
Linux nietzsche 2.6.32-35-generic #78-Ubuntu SMP Tue Oct 11 16:11:24 UTC
2011 x86_64 GNU/Linux
svnserve, version 1.6.6 (r40053)
    compiled Jun 5 2011, 14:51:47

Remote svn users can not commit/checkout, this was working perfectly but
suddenly is showing this "malformed network data" error

where can I submit a bug for this?

thanks,
