If you made no assumptions, you'd write no code.

...and if you write a try/except for every possible name or piece of code that 
may change in the future, you'll end up with an infinitely large piece of code.

Sorry, your logic is flawed. This is just 'one of those things' that happens 
when people change code that other code relies on. Sadly, ZCatalog has been 
particularly prone to that over the years...
