The problem was simply that the part didn't know it was complete.
	To let it know, I hooked up some loader signals, and now it works.

        * khtml/khtml_part.cpp:
        (KHTMLPart::init): Create the KWQKHTMLPart a little earlier so we have
	a chance to initialize the cache before it's used.
        (KHTMLPart::slotLoaderRequestStarted): Take this out of ifdefs.
        (KHTMLPart::slotLoaderRequestDone): Ditto.

        * khtml/misc/loader.h: Add a KWQLoader pointer to the loader.
        * khtml/misc/loader.cpp:
        (Loader::Loader): Create a KWQLoader;
        (Loader::~Loader): Destroy the KWQLoader.
        (Loader::load): Take out ifdefs around code that emits requestStarted.

        * kwq/KWQKHTMLPart.mm: (KWQKHTMLPart::KWQKHTMLPart): Call Cache::init().

        * kwq/KWQLoader.h: Add a class KWQLoader, with three signals in it.
        * kwq/KWQLoader.mm: (KWQLoader::KWQLoader): Initialize the three signals.

        * kwq/KWQSignalStubs.mm:
        (Loader::requestDone): Emit the signal using KWQLoader.
        (Loader::requestFailed): Ditto.
        (Loader::requestStarted): Ditto.

        * kwq/KWQSlot.h: Add an overload for slots with loader and cached object
	parameters so we can handle the new slots.
        * kwq/KWQSlot.mm:
        (KWQSlot::KWQSlot): Added slotLoaderRequestDone and slotLoaderRequestStarted.
        (KWQSlot::call): Added the new overload to handle those two signals.

        * kwq/KWQSignal.h: Add an overload for signals with loader and cached object
	parameters so we can handle the new signals.
        * kwq/KWQSignal.mm: (KWQSignal::call): Ditto.

        * kwq/KWQObject.mm: (QObject::connect): Remove the special casing that
	prevents complaints about slotLoaderRequestDone and slotLoaderRequestStarted,
	since we support those now.
