KURL is usually built on the stack (KURL blah) rather than on the heap (new).
When passing as parameter, prefer to pass objects by reference than by value.

This can't compile (url is an object, and you access it with "->").
and to set a URL to another one, just KURL a = b;
There isn't enough code here to see what could possibly be crashing anyway,
but those uses of pointers make it likely that you have an unset pointer somewhere.
