I seem to keep on getting this error when displaying a view that has been working for quite a while and I'm a little puzzled why its stopped working all of a sudden, gets everything ready and displaying on the sim/device and the crashes out with this error. Anyone got any ideas?

Well, the obvious answer is: You have a bug in your program. Seriously, there's little else that can be said from such a stack trace. There may be a myriad reasons for the bug (such as trying to access a released object, accessing an array out of boundaries, or any other number of things, and the place where the bug is doesn't necessarily have to have anything to do with the view in question).
