Did you ever get this resolved?
I’ve just had it pop up on my Production Premium CS5.5 install.
Have trashed the preferences file – doesn’t fix it.
Have reinstalled CS5.5 (clean install) – same issue immediately pops up.
Have done a complete system re-install – same issue again.
Re-installed Quicktime, tried older versions – doesn’t fix it either
Maybe it’s just affecting us Kiwis 🙂
