To reproduce, follow a link in listview that will cause the browser to be 
launched, then use the back button to go back to mixare.

Hi Daniele,

I think this has been already fixed,
and the fix on the development branch.

I tried to reproduce the issue, with the current development and I wasn't able 
to see the error.

In anycase, this is caused by "dead cycle" in dataView and MixContext, where is 
stored in MixView, mapView and listView; where MapView and ListView barely uses 
dataView.

I'm working on workFlow branch which should loose some of the coupling and 
document the code for future developers.

if the "mixare/development" has this issue too,
please add these lines in MixListView#onCreate() after super.onCreate()
Throwable tr = new Throwable();
Log.i("Mixare - Issue 137", "Intent= " + this.getIntent().getAction(), tr);

Regards,
