presentModalViewController crashes simulator

Hi everyone

I have a very weird situation, check out the snippet below which launches a ModelViewController for an iPad application:

// Load GuestDetailController
GuestDetailController *detaileController = [[GuestDetailController alloc] init];
if (searching) {
   // some code, but nothing relevant to the issue (checked that already)
} else {
   // some Code, but nothing relevant to the issue (checked that already)
}

[self presentModalViewController:detaileController animated:YES];

This works like a charm when running on an actual iPad, yet whenever I access this on the simulator it crashes and reports the last line of the snippet as its sore point (the error seems to appear in obj_msgSend which is called as a consequence of my presentModalViewController call). Maybe this is a bug of the simulator? I have looked at that code for hours now, but it seems fine to me.

Thanks for your ideas!

Edit: Here is a snippet from the crash report
