Narrow tang - this may be fine for kitchen work, but you can expect that a knife with a narrow tang construction wouldn't survive the rigors of any survival activity like chopping wood or pounding its blade down to split small logs.
Folding knives - this also includes multi-tools. A folding knife is not ideal in survival mode simply because it is not strong enough to perform outdoor cutting and slicing activities.
Huge knives - you've got Hollywood to blame for this. Sporting huge monstrosities like Rambo knives is not practical in the sense that a large knife will be unable to do some intricate work during survival situations. You need your survival knife to help you in setting up camp, trapping and hunting, and not in slaying large beasts in just one mighty thrust.
Hollow-handed Knives - while there are exceptions, this is a real liability in outdoor situations. Not only do you need to have a good grip on your knife while doing certain outdoor functions, a hollow-handed knife also means having a narrow tang, which easily breaks when doing heavy work.
What You Want In a Survival Knife Instead
Full tang - this is what defines the real strength of the survival knife. The handle (which is also the tang itself and is a direct part of the blade) is wrapped with some material for comfort.
