When inflating fragment which was previously inflated app crashes

I've been fighting with this same issue all day today. I got mine working earlier. Here's what I did: When changing the fragment showing, I first remove the old mapFragment, then do what I normally do when adding new fragments.

Fragment oldMapFrag = getSupportFragmentManager().findFragmentById(R.id.map);
if(oldMapFrag != null) {
    getSupportFragmentManager().beginTransaction().remove(oldMapFrag).commit();
    manager.popBackStack();
    ViewGroup container = (ViewGroup)findViewById(R.id.content);
    if(container != null)
        container.removeAllViews();
}

When I want to view the mapFragment again, I remove the previous fragment then inflate the view with the mapFragment again:

Fragment currentFrag = getSupportFragmentManager().findFragmentById(R.id.content);
if(currentFrag != null) {
    getSupportFragmentManager().beginTransaction().remove(currentFrag).commit();
    manager.popBackStack();
}
View mapView = inflator.inflate(R.layout.store_finder, container, true);

I don't know why getSupportFragmentManager().beginTransaction().remove(oldMapFrag).commit(); works in the first step because you shouldn't be able to remove fragments defined in XML, but this does work for me. I hope it helps.
