I have a different solution. If I un-check UK Holidays on my MacBook Pro (so it doesn't show on the Calendar), and wait a few moments for it to sync, then the iPad crash problem goes away ! Hope this works for you too.
Incidentally, I don't know if it's part of the problem, I use BusyCal2 on my MacBook Pro and unchecked the UK Holidays from that.
