---------------------------------+------------------------------------------
 I am following the PeepCode MacRuby 035 screencast and ran into a crash
 early on in development. I've attached the project that I was using.

 The crash is intermittent but pretty frequent (over 50% of the launches).
 I've seen several different stack traces thrown at the same time, so it's
 a bit random.

 To reproduce:

 1.) Open the attached project
 2.) Build and go
 3.) click on the Xcode window and then back on the application window

 Step #3 isn't always required.

 I am using Mac OS X 10.6.1 with the new Xcode 3.2 and the iPhone SDK
 installed. I am on an Intel Core 2 Duo laptop.

 I am using the nightly build: macruby_nightly-2009-09-29-1155

 Changing the NSLog statement to puts seems to fix the problem.

 Lots of noise in the console output:
