The problem with Ti seatposts is they are slippier, they slip more easily, I've had more issues than steel seatpost. Another reason to go steel on a long-distance touring configuration.
titanium also tends to stick to other titanium bits if left in contact without some anti seize used.
but seatpost failures from the seat post splitting down the circumference are quite rare. Usually the frame, seat post cap or saddle clamp gives up before the seat post does. If it happens, it's usually because someone had too much fun with a drill.
