[ksnapshot was indeed fixed rather long ago for this, but let's discuss the 
kdialog behavior]

The point is that making a non-existing button default never worked. But 
before it would just silently break, while now it asserts.

(and the assert says "defaultButton will return the value set by 
setDefaultButton", it can't possibly be a wrong assert, it just revealed the 
issue of calling the method with a non-existing button).

I guess your point is "KDialog should remember and make the button default 
once it exists". Hmm. It can be done indeed. I don't know if it's worth the 
additional complexity, but if you feel this should work, please review the 
attached patch. Unittest passes, of course.
