Here's how to tell Krazy to make an exception:

1. if you want Krazy to exclude this check for your entire subdir (eg, kdesupport/strigi)
     create a .krazy file in that subdir with the line
         EXCLUDE constref

2. if you want Krazy to exclude this check forinstalled header foo.h, then
     put this comment someplace in foo.h
        //krazy:excludeall=constref

3. if you want Krazy to exclude this check for method fooMethod(), then 
    put this comment at the end of the fooMethod() delcaration
       //krazy:exclude=constref

       eg.  const QStringList &Foo::fooMethod() const();  //krazy:exclude=constref
