Deeply nested dictionaries - should I look into a database or am I just doing it wrong?

QueueItem.x264['avs']['filter']['fft3d']['ffte'] would be 
QueueItem.x264.avs.filter.fft3d.ffte. I recently "migrated" from a 
syntax of - example - datetuple[fieldpositions['tm_year'][0]] (where 
fieldpositions was a dictionary containing a list) to 
datetuple.tm_year_start which is much more readable.

The advantage of a SQL(ite) database would be simple flat tables but 
accessing them would be more difficult.

Even a INI config file structure could match your problem.
