Debugger in an iPhone app session not launched from tapping a springboard icon

Question

I'm trying to debug an issue that only occurs when my iPhone app receives a push notification.

The trouble is I can't figure out how to get a debugger, or even view any NSLog output, when my app is launched in this way. Xcode gives me a debugger and the gdb console when it launches an app for me.

So how do I run my app in the debugger when Xcode does not launch my app for me?
