First of all, what are you trying to archive? 

In order to breathe life into these objects, you need to add some code, 
generated by yourself (brain and all..). Designers output is a suitable 
basement for this task (in terms of subclassing or calling into), but 
in no way it's meant to be exhaustive.

If you question the output of pyuic4, the very next thing to do is 
comparing it with the output of uic. Since that is the reference 
implementation for pyuic4, any significant differences should be dealt 
with, and I guess, if nobody jumps up and provide patches, Phil will 
sometime (depending on his priorities and importance..).

Since pyuic4 output is not meant for human consumption (apart from 
debugging purposes), a patch from you in this area is highly unlikely 
to be applied by Phil.. [Hint: sed is your friend for such tasks]
