I suppose I'm not the only one who have this problem...

there is a chest in the third house from the left(the first ohne is an inn) which can't be opened! It in front of a cupboard where you can find an Ether(I think it was an Ether) inside

Does anyone know how to open this thing and if noone knows, has anyone ever tried to use the rubbish-key from Mideel at the chest(before bursting it at the door in the Mideel weaponshop)??

can anyone help me??
