Buggy source:
@Override public Dialog onCreateDialog(Bundle savedInstanceState){
  AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
  builder.setTitle(R.string.uv_subscribe_dialog_title);
  View view=getActivity().getLayoutInflater().inflate(R.layout.uv_subscribe_dialog,null);
  final EditText emailField=(EditText)view.findViewById(R.id.uv_email);
  emailField.setText(Session.getInstance().getEmail());
  builder.setView(view);
  builder.setNegativeButton(R.string.uv_nevermind,null);
  builder.setPositiveButton(R.string.uv_subscribe,new DialogInterface.OnClickListener(){
    @Override public void onClick(    final DialogInterface dialog,    int which){
      Session.getInstance().persistIdentity(Session.getInstance().getName(),emailField.getText().toString());
      SigninManager.signinForSubscribe(getActivity(),Session.getInstance().getEmail(),new Runnable(){
        @Override public void run(){
          suggestion.subscribe(new DefaultCallback<Suggestion>(getActivity()){
            @Override public void onModel(            Suggestion model){
              if (getActivity() instanceof InstantAnswersActivity)               Deflection.trackDeflection("String_Node_Str",model);
              suggestionDialog.suggestionSubscriptionUpdated(model);
              dialog.dismiss();
            }
          }
);
        }
      }
);
    }
  }
);
  AlertDialog dialog=builder.create();
  dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
  return dialog;
}

Fixed version (ground truth):
@Override public Dialog onCreateDialog(Bundle savedInstanceState){
  AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
  builder.setTitle(R.string.uv_subscribe_dialog_title);
  if (!Utils.isDarkTheme(getActivity())) {
    builder.setInverseBackgroundForced(true);
  }
  View view=getActivity().getLayoutInflater().inflate(R.layout.uv_subscribe_dialog,null);
  final EditText emailField=(EditText)view.findViewById(R.id.uv_email);
  emailField.setText(Session.getInstance().getEmail());
  builder.setView(view);
  builder.setNegativeButton(R.string.uv_nevermind,null);
  builder.setPositiveButton(R.string.uv_subscribe,new DialogInterface.OnClickListener(){
    @Override public void onClick(    final DialogInterface dialog,    int which){
      Session.getInstance().persistIdentity(Session.getInstance().getName(),emailField.getText().toString());
      SigninManager.signinForSubscribe(getActivity(),Session.getInstance().getEmail(),new Runnable(){
        @Override public void run(){
          suggestion.subscribe(new DefaultCallback<Suggestion>(getActivity()){
            @Override public void onModel(            Suggestion model){
              if (getActivity() instanceof InstantAnswersActivity)               Deflection.trackDeflection("String_Node_Str",model);
              suggestionDialog.suggestionSubscriptionUpdated(model);
              dialog.dismiss();
            }
          }
);
        }
      }
);
    }
  }
);
  AlertDialog dialog=builder.create();
  dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
  return dialog;
}
