iOS Xcode 5.1 Crash Old Projects

[Blast12345]

I recently came back to Xcode to work on a new app (last used Xcode in April 2013). I'm wanting to look back at some old code, but whenever I open the projects Xcode promptly crashes. Is there some annoying issue that came along that everybody knows about except me who is out of the loop? I can make a new project, save it, and open it just fine - the problem is only projects made with older versions of Xcode.

Thanks!

Just for fun, I opened a copy of an iPhone project that I hadn't touched since 2009. Xcode 5.1 built and ran the app in the Simulator just fine. Ancient iOS 2.x code. Lots of warnings. No fatal errors.

I appreciate you trying that. There must be something not quite right about my installation. I tried deleting Xcode and are downloading it, but perhaps I should try that app remover (I can't remember what it is called) so I can get the freshest instl I can.

I used AppCleaner and that made no difference. When I reinstalled XCode the problem was still present. Does anybody else have any input?

Here is the first part of the crash report:
