Lines 49 to 52 in f0df04a

	if (context.conditional) {
	stark_sign_display_master_account();
	pairs[count].item = "Master Account";
	pairs[count].value = strings.tmp.tmp;

When there is a self conditional transaction this field is not displayed on the nano.

Closing because starkware is no more in ethereum app
