Don't load it in the background then, load it in the foreground. We
currently have no easy way of doing this, but IMHO it would make sense
to add a KJob subclass that contains a schedule function that basically
does:

QueueJobEvent* m = new QueueJobEvent( this );
QApplication::postEvent(Core::self()->runController(), m);

And RunController than catches the event and simply does:

m->job()->moveToThread( this->thread() );
registerJob( m->job() );

Unless of course you need the language plugin in the background thread,
that would make it a bit more complicated (as in, wait for the
plugin-loaded signal by running a local event loop).
