Yes Jim, the small splitting by the zipper is very common with those pouches including Doug's pouch causing the pack to lose it's ability of waterproof plus the zippers over time will open up or crack open in your pocket and the nylon or what ever it is made of will get hard in time. The only thing I have found so far to prevent this is a aqua pack so far (see link)for the size. If you had room, I would go watershed which is hands down the best water proof bags I have found less DUI products which are way to expensive. The problem with watershed is they do not make packs that small and I use them as liners in my BOB with a depth rating of 300 ft Sea Water. I am still testing the aqua pack key master for durability and so far it is still holding up like a champ. The key master has a lower signature than Doug's kit, more comfortable, smaller and 100% no nonsense waterproof. I carry it everywhere I go and go swimming with it from time to time to keep checking the integrity of the waterproofing. Anyway +1 on aquapack, if your not concerned with waterproofing then the nylons are fine but they will leak in time.
