Trouble with new Pantheon

[Tankinator]

Hello,

I am trying to add a couple of new pantheons.

Initially, one of them was supposed to add culture to city base on the number of coast tiles owned.
I wasn't able to make it work ("crash to menu") so I tried to make an adjacency bonus for holy place and coast, thinking that if I managed to do so, it would be easier to make my original plan, based on this new understanding..
When I can choose my pantheon, the pantheon screen refuse to open, and so the game is definitely locked. Pressing the button had no effect.
I spend the all evening trying to fix it, without success...

EDIT : I managed to redo my initial project from scratch, based on Seaport gold bonus. Still impossible to open the pantheon window.
My new code :

<GameData>

        <Row Type="BELIEF_MUSIC_OF_THE_SEA" Kind="KIND_BELIEF"/>
    </Types>
    <Beliefs>

Can someone see my mistake ?
and/or does someone know if it is possible to apply a bonus yield to all tiles of a certain type ?
