done some more research on this and it turns out to be a stupid problem that comes from subversion libraries:

from path.c:
#ifndef NDEBUG
static svn_boolean_t
is_canonical (const char *path,
               apr_size_t len)
{
   return (! SVN_PATH_IS_PLATFORM_EMPTY (path, len)
           && (len <= 1 || path[len-1] != '/'));
}
#endif

The problem was the trailing slash. ;) Now it works just fine.
