Error accessing svn repository via http uid

I am trying to access a subversion repository via a uid-url. This fails with an svn client error:
user@clientpc:~$ svn info https://myserver/_12
svn: E235000: In Datei »/build/subversion-Z4OiCa/subversion-1.13.0/subversion/libsvn_client/util.c«, Zeile 96: Assert-Anweisung schlug fehl (svn_uri__is_ancestor(pathrev->repos_root_url, url))
Abgebrochen (Speicherabzug geschrieben)

Access via the name of the repository works fine.
user@clientpc:~$ svn info https://myserver/mytest
Pfad: mytest
URL: https: //myserver/mytest
Relative URL: ^/

What’s going wrong here? Can anyone help me?

Thanks for any help!
