That's what Apple said - the app got crashed for them against iPad 3, there was no log produced:
The application crashed on the third generation iPad running iOS 5.1, there were no crash logs produced.
What i did is that i re-signed exactly the submitted .app, installed it on all the iPods, iPhones and iPads i had (unfortunately not iPad 3 - this case was tested against the simulator).
The icons property at info.plist looks good, all the resources are in the bundle. Confusing thing is that another app with the same code but another configuration is approved. Let me stress it out - both the configuration was tested with the submitted .app files.
Any clue, shared experience or workaround ? The current plan is to make some slight changes and resubmit the rejected app.
Apple Tech Support was able to find the crash report, no matter how they did it and why they said there's no report in the first place.
The problem was that with the accessibility turned on the UINavigationBar class called +(void)initialize on the very application startup.
