title: Crash/SIGABRT when I try to present a UIPopoverController
body: <p>Hi I am at my wits end with what I am doing wrong here. I am using ios5 and nothing crashes if I do not call presentPopoverFromBarButtonItem. Has anyone experienced anything similar? I checked the apple developer forums, google, stack overflow and couldn't find anything.</p>
  
  <p>Running bt on gdb didn't reveal any hints either.</p>
  
  <pre><code>UIViewController *viewTwo;
  viewTwo = [[ViewTwo alloc] initWithNibName:@"ViewTwo" bundle:nil];
  
  UIPopoverController *popover;
  popover = [[UIPopoverController alloc] initWithContentViewController:viewTwo];  
  
  [popover presentPopoverFromRect:[theButton bounds] 
                           inView:theButton 
         permittedArrowDirections:UIPopoverArrowDirectionLeft 
                         animated:NO];
  </code></pre>
