Symptom: 
Try to list all the issues by using "group on" option  
on “creator”, “assignedto”, "actor", "category" property
Then got "Templating error” page.

Possible Reasong/Solution:
This function works fine for the roundup which use 
default anydbm as the 
backend database, but not on the roundup which use 
postgresql as the backend 
database. So will check if there is any difference 
between the backend 
database.
