The reason for checking .description is that I want to be sure that an 
exception raised from fetchXXX is because an error has occurred rather than 
no rows to return. And I want this to be the case regardless of the type of 
query that has been passed to execute(). The check of .description (I think) 
is the only way to be sure that a 'select' type query has been passed to 
execute().

The background to this is in the "[DB-SIG] Is there a better way of doing 
this?" thread from last week.
