This sort of thing has been a problem for a long time. Back in the early days, a high INT just meant you knew more languages or spells, and that was it. It was never meant to affect the choices the character made. The "role-playing" started to confuse that issue.
With a game like Pathfinder, taking that old-school approach is probably best. That is to say, the PC is the player's playing-piece in a game of adventure, and the player makes his decisions for better or worse.
Verisimilitude is important in that sort of game, however, and if some fraction of the people at the table agree that something "wouldn't happen" then it should be correctible. Unfortunately, that's the land of house rules and social contract. How long can you wait to call for a do-over? How many people have to complain before something is deemed "unrealistic"? That sort of thing is unique to each table.
That said, the "building a campfire in the tree burns down the tree HAW HAW" seems like it'd be an awfully d***ish player-screw 99% of the time.
