Thinking about this, common libraries shouldn't popup message boxes at
all. Indeed, like you said, how does it know if it's an user or machine
generated is calling. Me thinks it should return -EMALFORMEDURL or throw
a KIOMalformedUrlException object with some hints what was wrong, and
location bar can show a message to the user while kjs triggers a script
error, no?
