Perhaps bamf_view_get_name() is returning NULL before this loop:

window_name = bamf_view_get_name (BAMF_VIEW (window));
g_debug ("checking window name '%s'", window_name);

  for (i = 0; i < G_N_ELEMENTS (ignored_names); i++)
    if (g_str_equal (ignored_names[i], window_name))
      {
        g_debug ("window name '%s' blocked", window_name);
        ignored = TRUE;
        break;
      }

       on it" (lp: #953620)
