If you overwork the dough you may experience it. But there is a solution! When you cover the pan with the dough, there will be some leftover dough that you trimmed from the sides.  If it tears, simply cover the baked crust with a very thin layer of leftover dough. This leftover dough should be sticky as it should stick to the crust. You can press the dough between your fingers to thin it out and then gently place it over the torn part.  Keep in the oven for a few minutes until it completely bakes.
