Bad survey archive crashes Park Observer

[regan-sarwas]

The attached survey archive crashes Park Observer circa 2.0.0.beta4/5 on iOS 4.2 (or so). It was was presumably created with an unreleased/buggy version of PO2.0, so it should be hard to recreate a bad archive like this in the wild. However, I would like to ensure that Park Observer doesn't crash, even with bad input.

It crashes app with EXC_BAD_ACCESS in apple core data code when closing survey. I can still load it, edit it and save it without problem. just not close it.

Note that the .poz extension has been changed to a .zip extension for uploading to github, and for inspecting the contents. to load into park observer, change .zip to .poz.
