Dying through a door transition softlocks the game

I just had unfortunate timing with a friend: I ended up dying in the middle of a door transition, specifically in Thieves Town dungeon, in the top-right door of the room to the right of the big chest.

The game decided not to send me to the Game Over screen, I couldn't move, and I couldn't save+quit, either... Can anything be done to prevent/fix this?
