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

Question

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".
