Universal iPad App rejected because of launch crash that I can't reproduce

I'm very frustrated with this problem. After one week of waiting my universal iPad app has been rejected because "is crashing on launch on iPad running iPhone OS 3.2 and iPhone 3GS running iPhone OS 3.1.3 and Mac OS X 10.6.2."

Unfortunately I can't replicate the problem, I've tested in debug and release modes and the app works just fine. I even created an ad-hoc configuration and test it in other devices and everything works fine.

I should clarify that this is an update to a current iPhone application and I'm using the same distribution profile as the original iPhone app. Also, I checked everything before building the universal app following this entry:

Here are the crash logs that Apple sent me:

The app does not do anything other than loading a local HTML into a web view after the app it's launched so I don't understand why it says "failed to launch in time"

Any help will be very much appreciated.

WOW !!!! Now, this is extremely, extremely frustrating. After lots of hours and even days of debugging, looking at my code, testing in different scenarios, asking questions and 2 rejections, Apple wrote me an email today (18 days after my first submission):

"... This is an issue with the submission process and not with your code. iPhone OS Engineering is investigating the problem...."

You can imagine how I feel right now. Thanks to everyone who help me trying to figure out this "crash".

Are you trying to load the web view from applicationDidFinishLaunching? Are you sure the tester can connect to your server?

The crash is not a crash at all, it is the system forcing your app to quit because it took too long to start. Move everything you can out of applicationDidFinishLaunching so it can finish, well, launching.

If you are loading a web page, what happens when you disable all networking (airplane mode) and launch? That is one of the standard tests they run, so you should too.

I would try simulating a low memory condition and see how our app handles it.

You said you copied your code over. Did you also copy over your local resources? ie your html file? And you're sure it isn't just linked in? Is it being included in the build? If the file is just linked in to the bundle it may explain why it launches for you but not for them.

In the future (and maybe you want to try this to see if it works out any better for you) the proper way to upgrade your app to a universal app is to use the Xcode file option Upgrade for iPad (or something like that) it will do all the necessary work for you to make it iPad compatible. Step by step is on apple's site, just do a google search how to create universal app.

Just submit the same app again to Apple without any changes. Someone else will review it and They will approve it. Trust me, I've done it before. Apple approval team is downright crazy. On devices, apps crash due to memory issues. This is something that can't be reproduced. From your crashdump it looks like that.
