 Thanks, I would have posted almost exactly the same, you just were a bit
 quicker ;)

 BTW the string {{{NULL}}} is also the representation for undefined string
 attributes in the attribute editor.   Searching for (or editing to) a
 literal string "NULL" will(/is) currently impossible - maybe there should
 be a way to set the NULL representing value in options.
