Apparantly one of the functions is not preserving the current buffer.
You might try using the debugger, which is not yet fully integrated
into jed.  Nevertheless, you can try the following to get an idea
about how it will eventually work:

1.  Put the following code in your .jedrc file:

autoload ("sldb", "sldbsock");
define _line ()
{
   variable beg, end;
   push_spot ();
   push_mark ();
   bol ();
   beg = bufsubstr ();
   pop_spot ();
   push_spot ();
   push_mark ();
   eol ();
   end = bufsubstr ();
   pop_spot ();
   
   return strcat (beg, "^", end);
}

define debug (files)
{
   if (NULL != getenv ("DISPLAY"))
     {
	variable pgm = path_concat (_slang_install_prefix, "share/slsh/scripts/sldb");
	pgm = sprintf ("(sleep 1; xterm -e '%s' --pid %d) &", pgm, getpid ());
	() = system (pgm);
     }
   sldb (files[0]);
}

2. Run jed via:

   jed -hook debug svn.sl

3. At the (sldb) prompt, you can use

    (sldb) p _line

   to see the current line.

4. Set a breakpoint in the desired function, e.g., cvs_list_dir:

    (sldb) break cvs_list_dir

5. Tell sldb to continue:

    (sldb) cont

6. When the cvs_list_dir function is called, sldb will regain control

    (sldb) 

7. Use next, step, and other sldb commands as described in the sldb
   tutorial at:

      <http://www.jedsoft.org/slang/doc/html/slang-19.html#ss19.2>

Hopefully this will help you located the problem.
Thanks,
--John
