CALayerInvalidGeometry uncaught exception in AddressBookUI

Originator:futuretap
Number:rdar://8828308 Date Originated:06-Jan-2011 05:38 PM
Status:Closed Resolved:
Product:iPhone SDK Product Version:4.2
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
We received several crash reports with

*** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [0 nan]'

originating from the AddressBookUI framework. Please see the crash reports attached.
While we were not able to reproduce this particular backtrace, we created a little test project with an ABPeoplePickerNavigationController that crashes *in the simulator* reproducibly with

*** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan -0.5]'

We were NOT able to reproduce the crash on our test devices (iPhone 4 running iOS 4.1 and iPhone 3GS running iOS 4.2.1). However, this might be due to specific circumstances not met on our devices.


Steps to Reproduce:
- Reset the simulator content (to make sure we have a sane AddressBook)
- Create 2 contacts using "Contacts": one with just a name, one with name and an address
- Build the attached test project and run it in the simulator.
- Tap the "Address Book" button
- Select the contact with address
- Go back
- Select the contact without address

Expected Results:
The contact without address should be shown.

Actual Results:
The app crashes. Crash report "ABPersonVCBug.crash" attached.

Regression:
Happens in the simulator on iOS 4.0.2, 4.1 and 4.2. Not reproducible on our test devices.

Comments

A workaround for me was to be add kABPersonFirstNameProperty, kABPersonLastNameProperty and kABPersonOrganisationProperty to the list of displayed properties: 

ABPeoplePickerNavigationController *picker = [[[ABPeoplePickerNavigationController alloc] init] autorelease];
NSMutableArray* properties = [NSMutableArray array];
[properties addObject:[NSNumber numberWithInt:kABPersonPhoneProperty]];
//Needed to stop mysterious crash if no number is present in contact and it is selected a second time rdar://8828308
[properties addObject:[NSNumber numberWithInt:kABPersonFirstNameProperty]];
[properties addObject:[NSNumber numberWithInt:kABPersonLastNameProperty]];
[properties addObject:[NSNumber numberWithInt:kABPersonOrganizationProperty]];
picker.displayedProperties = properties;
