Oh, when I build the app against the Qt 4.6 beta it doesn't lock up... it just takes a hell of a long time and creates a nicely laid out pdf wherein all the text is replaced with capital As in boxes. I really do blame Apple for this.
Nice. Real nice.
EDIT: Also, Hey Apple thanks for completely horking the X11 libs and making it nearly impossible to update them to a current version forcing people to use the xquartz ports. I think I want to downgrade from 10.6
