I have built bash from devel branch and I am still able to reproduce this bug. 
Also, this bug is reproducible if I try to complete path names instead of 
arrays.

# ls /home/situ/Des<TAB>bash: !ref: unbound variable

I can only relate one change from devel branch with this bug, however it does 
not handle all the cases :

@@ -3140,7 +3147,12 @@ bash_filename_stat_hook (dirname)
   if (should_expand_dirname)  
     {
       new_dirname = savestring (local_dirname);
+      /* no error messages, and expand_prompt_string doesn't longjmp so we 
don't
+        have to worry about restoring this setting. */
+      global_nounset = unbound_vars_is_error;
+      unbound_vars_is_error = 0;
       wl = expand_prompt_string (new_dirname, 0, W_NOCOMSUB);  /* does the 
right thing */
+      unbound_vars_is_error = global_nounset;
       if (wl)

nounset should be turned off for all completions and not just for one specific 
case.
