Since iOS 4.1 I have noticed a crash in the background when a significant change event occurs:

There is a developer forum question for this issue from another user. Not sure if this is a bug in LocationTest or a 4.1 problem

I'm seeing a lot of logs for the crash below. The app is running in the background.

If you run the analyzer you'll see that there is a leak of NSString on line 45 of LocationTestAppDelegate.m, the variable "content". If you autorelease the string it should be fine, but my preferred fix would be to use the class method stringWithContentsOfFile:encoding:error: instead.
