Runtime error on simulator with SDK 3.0.12 and Fenix 3

For some reason, when I try to run some apps in the simulator with SDK 3.0.12 and select Fenix 3 (or derivatives), I am getting a run-time error that does not show up when I switch back to using SDK 3.0.11. This is on the MacOS version of Eclipse and the SDK.

Error: Symbol Not Found Error
Details: Failed invoking <symbol>
Stack:
- initialize() at /Users/douglas/develop/garmin/widgets/connectiq-widget-temperature/source/TemperatureView.mc:23 0x10000429
- getInitialView() at /Users/douglas/develop/garmin/widgets/connectiq-widget-temperature/source/TemperatureApp.mc:43 0x1000018a Symbol Not Found Error

The offending line of code within TemperatureView.mc is within the initialize() method as such:

var deviceSettings = System.getDeviceSettings();

Is this a known issue? I searched the forums and didn't find anything obvious.
