Unfortunately, you'll get ambiguous ctors with most derived classes
then, since there's an implicit type conversion ctor for
QString->KGuiItem.

Hmm, if that was made explicit... Is adding the explicit keyword to a
ctor BC? I guess so. But is it SC, too?
The other option is to remove the default for the second argument to the
4xQString KGuiItem ctor. But that would be even more SIC, wouldn't it?

I tried the explicit keyword. When doing this, very many users of 
KDialogBase failed to compile, since the user-defined buttons take 
KGuiItems, but the users only provide QStrings most of the time :-(
Removing the default argument will lead to the same problem.
