Return to app from "Maps" causes crash

App-type: mobile Titanium SDK version: 3.1.1 (06/15/13 16:09 f7592c1) Platform Android Device: Android physical device (samsung S2) OS: Windows Titanium Studio: build: 3.1.0.201304151600

The user can open "Maps" from my app via

var intent = Ti.Android.createIntent({
    action : Ti.Android.ACTION_VIEW,
    data : 'geo:0,0+?q=' + L('imprint_search_location')
});
Ti.Android.currentActivity.startActivity(intent);

On customer feedback, on an older smartphone (S1), the app crashes when the android return button is clicked. Any experience for this with older versions/smartphones?
