svn move fails with "No repository found "

Hi everyone. I have read other having this problem that is related to
bad repositories configuration but I can't figure out how to fix mine.
I show you command line output to be sure nothing is reported with
errors:

ildella /home/svn: svnadmin --version
svnadmin, version 1.5.4 (r33841)
   compiled Aug 7 2009, 02:02:06

where "ildella" is the machine, /home/svn the subversion home with 2 subfolders:

ildella /home/svn: ls
public/
private/

The command

ildella /home/svn: ps auxww | grep svn
root 4424 0.0 0.0 111036 356 ? Ss Aug21 0:00
svnserve -d -r /home/svn/

Now I am using two dfferent repositories with different users since
more than a year.
Today I tried a move from my local workspace. The project is "phaedra":

ildella_at_ildella-laptop:~/projects/personal/phaedra$ svn info
Path: .
URL: svn://192.168.1.50/public/trunk/phaedra
Repository Root: svn://192.168.1.50/public
Repository UUID: fe040772-396e-42cf-9f8a-8afd5813f1ac
Revision: 525
Node Kind: directory
Schedule: normal
Last Changed Author: ildella
Last Changed Rev: 525
Last Changed Date: 2010-09-06 15:59:36 +0200 (Mon, 06 Sep 2010)

And the command fails like this

# svn mv svn://192.168.1.50/public/trunk/phaedra svn://192.168.1.50/private/
svn: No repository found in 'svn://192.168.1.50'
