iPhone App crashing on startup on some devices (not all)

I'm starting to get desperate and I need advice. Here's the situation:

The crash logs do not tell me anything useful. Here is one, perhaps someone smarter than me knows what happened:

As the only reference to my code in the report is to main.m, here it is:

            #import <UIKit/UIKit.h>

            int main(int argc, char *argv[])
            {
                NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
                int retVal = UIApplicationMain(argc, argv, nil, nil);
                [pool release];
                return retVal;
            }

So here is my question: How can I determine the cause? What can I do to get more information on this crash (I can send versions to someone who experiences this crash)? What can I do to prevent it?

Any advice is much appreciated and thank you in advance!

UPDATE:

I found the solution and it was a silly mistake on my part.

The MainWindow.xib could not load when there was no localization for the device's language. I always thought, it would fall back English, but it did not (anymore).

In previous versions, this was never an issue. I don't know why this behavior changed.

Thanks for all the replies, you helped me search in the right direction!

The application is trying to read the main nib file, as specified in your app's Info.plist file.

In the plist file there is an entry like

NSMainNibFile -> MyMainWindow

which UIApplicationMain uses to load your initial view controller from. This file seems to be damaged. A common error is to use a custom class for a contained object and then change/remove that class later without changing the nib file.

To further understand the error it would be very helpful to know the description of the exception that's being raised. You'll find that in the console log.
