xCode device logs not populating after application crash

问题

I'm getting a crash on my iPad 2 when building my Corona SDK app with a distribution profile, and putting it on my device via a USB cable. I'm testing a bug that happens when the internet is not connected (not sure if relevant). When the app crashes, the devices window's output stream states that it's storing a crash report (http://pastebin.com/Qa3BeaJ2), but then the crash never shows up when I push the "view device logs" button. When I push that button, I get an error message. Is resolving this the secret to getting my crashes to show up in the device logs?

Thanks!

UPDATE: It's now 10 PM. I've been checking the device logs throughout the day...and I just NOW got an update from 5:46 PM. What the hell? It's extremely short, and says:

OK, I was able to populate my crash. Here's how I did it:

• Synced the device with iTunes
• Opened ~/Library/Logs/CrashReporter/MobileDevice/< Device Name >
• Found a folder named Retired (no idea why or what this is)
• Inside was my crash log named blah.blah.beta
• Added a .crash extension
• Dragged it into Xcode's View Device Logs window
