If you acquired those sets from the booty, there was something flaky going on, but the same sets from the original source were fine. I had the same crashing problems, and then waited an age to finally get my mitts on the originals for testing.
If you still want those sets, try the booty again. I can't tell if those sets were updated (the booty needs a better system for indicating fixed files really, really badly), but I forwarded everything I had to the fine pirates there.
I probably did. Thanks for letting me know, I just removed them as I found some great Tikki related things from Parsimonious.
