Hmm, the relevant bits of getContents are (both for CMF 1.0 and
the head of the CVS repository)::

    # CMFCore/DirectoryView.py, line #97
    try:
        self.data = data = self.prepareContents(registry,
            register_subdirs=changed)
    except:
        # DEBUG
        import traceback
        traceback.print_exc()

I can't see how that code could *possibly* yield the traceback
you post -- did you trim it at all?  At any rate, that code is
broken;  having caught the exception in order to print it, it
doesn't re-raise it.  For the nonce, please try adding

         raise

just below the last line of the snippet.

I find that error message deep in the bowels of the Python
2.0 C source::

  # $PYTHON_2/Parser/parsetok.c, line #81
  static node *
  parsetok(struct tok_state *tok, grammar *g, int start
          , perrdetail *err_ret)
  {
      parser_state *ps;
      node *n;
      int started = 0;

      if ((ps = PyParser_New(g, start)) == NULL) {
          fprintf(stderr, "no mem for new parser\n");
          err_ret->error = E_NOMEM;
          return NULL;
  }

So, it looks like your system is running out of memory, but
the DirectoryView suppresses the error, and hence you get a core
dump.

Please submit a tracker issue for this problem:

Do note your version of Python on the issue -- that was most
helpful for tracking down the source of the exception.
