I initially knew what was wrong when you said that if you put the tag 
into the <widget> it works. So this helped a lot. Thanks.

AFAIK it's a matter of taste whether this is good programming style. 
Personally I prefer it this way because if you resize widgets (read: 
e.g. change the contents of a label) or add widgets the whole structure 
remains sane. IMHO a depth of four boxes inside another is perfectly 
manageable. But my coworker prefers tables (which allow two dimensional 
adjustments of each widget, not one dimensional) which I hate once 
reaching a certain depth.

If I need controlled space between widgets in a box (and "pack_start, 
pack_end, box expanding, both widgets not" is not sufficient (I doubt 
that)) I usually put an empty label between them.

Try to OOize your widget structure by using 'separate class' for complex 
substructures or use custom components which are reusable (!) (tell me 
if the overview in the users manual is not clear enough).

If you want an example take a look at e.g.
