Strange error message: Unable to open an ra_local session to URL

Hi,

for one repository I get a strange error message:

the command below does work, thus it should be a javasvn bug:

svn list file:///home/codebeamer/cb4/repository/svn/intl_inc

I think .../intl_inc/db/format really does NOT exist but
.../intl_inc/format.

How can I fix the problem?
