Uncaught Exception on launch from Push Notification

[paul.obeda]

I am able to register my device and send a push notification (sandbox
cert), but when the alert launches my app it immediately crashes ...
any ideas?

Note: this happens whether I use the default alert and click "View",
or the no-button alert (which launches the app by default).

Thanks in advance!
