Sorry, that was I mistake: if I run with python custom widgets (the 
plugin example), I experience the problem. If I run without any python 
custom widgets (so I guess the python plugin is not being used), 
everything works fine.

The dialog is created as expected, but if I try to add another default 
button (say "Apply" button), the other two buttons disappear. This can 
be seen in the Property Editor for the QDialogButtonBox, where I can 
only select one button at a time (and the "NoButton" field is checked 
and unactivated).
I was just wondering if this happens only to me.
