Hi bartek

Currently, in various catalog method (stock, movement, item ...) we check 
wether we should index the object in the method.
For exemple, z_catalog_movement_list first check the list of objects that are 
actually movement (using isMovement attribute) and only catalog them if the 
attribute is true.
So in your case, you can just filter the list of objects, using for example 
getPortalType. 

But this may still fail for empty emails, you have use "optional" attribute to 
dtml-sqlvar so that it doesn't complain with None values.

-  <dtml-sqlvar expr="getUrlString[loop_item]" type="string">
+  <dtml-sqlvar expr="getUrlString[loop_item]" type="string" optional>

Another solution can be cataloging objects only if getUrlString is not None.
