I can verify. The fighter who got hit by the trap is mathematically about as good as a rogue at finding traps, being an Expert in Perception. He rolled a 31 on his check to find the hazard, but a 32 was required.The point of having a "thief" character is that his or her odds of finding and disabling the trap should be drastically better than anyone else's.
In their blind drive towards balance, this is yet another thing Paizo completely forgot about
