This is probably because you are not passing the namespace to the DTML
method. You need to do this explicitly when you call a DTML object in an
expression. It is done for you when you call one by name. Try the
following:

  <dtml-with db_stuff>
     <dtml-var "db_query(_.None,_,...)">
   </dtml-with>

This will pass the namspace (through the _ variable) to your dtml method
which should allow it to find the other objects in the db_stuff folder
and elsewhere.
